Outlook for NEM 2019 – analysing scope for meteorological events

Dr T.Vasudevan, MD, an Anaesthetist by profession has been observing local Garbottam at Cuddalore since January this year. I am grateful to him for taking time to watch the sky everyday to contribute to our understanding of the way astro-meteorology works in bringing out rainfall.

A combined analysis of the Daily Garbottam of Chennai and Cuddalore along with the planetary triggers show some patterns of meteorological events in September, October and November.

Meteorological event indicated in September

Generally a meteorological event such as formation of Depression or cyclone happens when

  • Mercury / Venus crosses Mars to come right behind Venus / Mercury in rainy season
  • Mercury or Venus crosses Sun or other planets to come in the lead of all planets
  • Mercury or Venus enters the next sign in rainy season while coupled in planetary yoga.
  • Mercury and Venus cross each other from behind (rather than in opposite directions)

Planetary Yogas present in September:

  • Mercury –Venus closeness begins on 6th September and lasts till November 11th
  • No spoiler present as far as I could see.

In the table below the last column gives Garbottam based rainfall dates for Cuddalore and Chennai if present on the dates of planetary yogas.

Date in 2019 Planetary event Rainfall prospects   Cuddalore / Chennai Garbottam
Sep 3rd, 4th Mercury crosses Sun & Mars. Comes directly behind Venus Trigger to rainfall. Genesis of meteorological event Cuddalore: moderate
Sep 6th Moon conjunct with Jupiter in watery Scorpio Spurt in  rainfall Cuddalore: 7th to 10th  continuous.   Chennai: 8th, 9th brief
Sep 10th Mercury crosses Venus Both enter Virgo simultaneously Meteorological event. Heavy rainfall. Landfall if cyclonic. Cuddalore 10th

Planetary Yogas continue in September

Date in 2019 Planetary event Rainfall prospects Place
Sep 10-25 Mercury + Venus in Virgo Very good Chennai:11-15 Cuddalore: 23 South TN, Kerala, Kaveri, River basins of South
Sep 12 Venus ends combustion Spurt in rainfall South India
Sep 18 Saturn ends combustion Spurt in rainfall West India.
Sep 20 Mercury ends combustion Spurt in rainfall South India Chennai: 23, 23

Favourable planetary Yogas in October.

October is likely to be an important month with 2 major planetary yogas being present without any obstruction.

  1. Venus and Mercury combine in earthy sign of Libra in close degrees.
  2. Venus begins transit in Swati in the western sky
  3. The combined effect of these two will give maximum rainfall from NEM in October.
  4. Chennai also stands to benefit in this month
Date in 2019 Planetary event Rainfall prospects Place
Oct 3-18 Mercury + Venus in Libra Very good Chennai:1st to 12th Frequent Cuddalore: 9th to 12th South West TN. Interior Peninsular India
Oct 9 Venus enters Swati Spurt in rainfall South India
Oct 18- 24 Ven+Mer+Sun in Libra Widespread rainfall South, South West India.
Oct 24 Mercury enters Scorpio to join Jupiter Spurt in rainfall South west India Chennai: 22, 23
Oct 24 – 28 Mer + Jup in Scorpio Widespread rainfall Chennai: 20-28 Cuddalore: 20- 29 frequent
Oct 26 Mercury begins combustion Spurt in rainfall South, South West India.
Oct 28 Venus enters Scorpio to join Jupiter + Mer Spurt in rainfall South, South west India  
Oct 29 evening Moon enters Scorpio to join Mer+Ve+Ju Spurt in rainfall South, South West India.
Oct 31 Mercury begins combustion  at 1 degree behind Venus Spurt in rainfall South, South west India  
Nov 10 Mer-Ven closeness ends Rains until this date Cuddalore: occasional rains till then South, South West India.
Nov 11 Venus exists Anuradha  Rainfall ceases after this South, South west India  

Favourable rainfall Yoga in November

The next trigger period comes in November when Sun, Mars and Saturn start moving in alternate signs. This was found to be a sure sign of rainfall in the past. The date starts on November 10th – a day before the closeness of Mercury and Venus comes to an end. Chennai Solar Garbottam does not show any indication of rainfall at that time. However Daily Garbottam of Chennai gives twin dates, with the former coming between November 13th 23rd.

Similarly Cuddalore gives twin dates with the former coming between November 1st to November 25th.  

This year will be a test case to confirm which date works.

The trigger factor I noticed was from 10th November to 16th November when Sun and Mars will be Libra and Saturn in Sagittarius in alternate sign. With an unafflicted Venus in watery sign rainfall can be expected in West or interior Tamilnadu. Saturn’s position shows rainfall in east coast too. 

The trigger days are (1) 10th November when Mars enters Libra to join the Sun, (2) 11th November when Mercury crosses Sun in retrogression.

The next similar position of Mars, Sun and Saturn happens between 16th December and 25th December. Those days are yet to be covered by daily Garbottam.

Outlook for Chennai rains: July – Mid-December 2019.

At the time of writing this, the daily Garbottam observation period is almost over, because with the arrival of Aadi month, the corresponding rainfall month shifts to Margazhi (6th month from Aadi). The daily Garbottam observation somewhat matches with solar Garbottam observation done in Margazhi last. In this post let me share the findings, after stating two important observations for late arrival of SWM and lack of rainfall so far in general.

Confirmed observations that facilitate rainfall in 2019:

  1. Mercury and Venus must be in close degrees.

Known as Budha- Shukra Sameepyam, the closeness of these two brings out rainfall. This is repeatedly confirmed again and again in the 4 years of my observation of astro-meteorology.

For this year I wrote in January 17th blog the following table of closeness of these two planets. Rainfall pattern had followed these dates only so far. This observation is for general, overall rainfall scenario for India as a whole.

Pic

After the early rains lasting till May 21th, the next widespread event of rainfall is about to happen from July 22nd to August 14. Within this period the planetary yogas and daily Garbottam determine rainfall at a given place.

The above table shows the next probable period between September 6th and November 11th. The dates show an early NEM favouring Tamilnadu or a fused SWM end and NEM begin date favouring regions of SWM too. The next confirmed planetary yoga falls within this period.

  1. Venus in western sky in Swati, Vishaka and Anuradha favours rainfall

The location of Venus in certain stars in west or eastern sky during rainy months had greatly helped or spoiled the rainfall scenario. This was confirmed in two seasons in the past. Please check my observation written on January 27th.

Pic

The transit of Venus in the west from Swati to Anuradha (Anusham) happens between 9th October and 10th November this year. This transit coinciding with Budha-Shukra Sameepyam is an additional favourable feature to ensure rainfall mostly benefiting NEM regions. Local Garbottam would reveal the exact regions that are going to be benefited.

Having stated the favourable transits, let me state the unfavourable transits too.

Confirmed observations that spoil rainfall in 2019.

  1. Planets in opposition to Venus and Mercury.

Saturn and Jupiter are long term planets seated in the same sign for a long time. If they happen to be located in signs exactly opposite to Venus and mercury, rainfall is affected for nearly a month till the quick moving Venus and Mercury move away from the direct opposition. We should remember that Mercury brings favourable wind and causes cyclones when joined with or crossed by Venus. At that time Saturn or Jupiter or Mars must not be exactly opposite to them. The location of other two long term planets, namely Rahu and Ketu do not contribute to this. On the contrary if they are in close degrees to Venus, Mercury and Moon, they trigger rainfall.

In the following diagram, the closeness of Venus and Mercury as seen from the earth is ideal for rainfall. However if planets happen to be directly in the opposite side of the orbital plane of these two planets, rainfall is affected. This alignment conveys that planetary rays on the earth’s atmosphere do create some changes either by favouring or spoiling rainfall.

Pic

Suppose this happens in the pre-monsoon period, pre-monsoon rains get affected. It was so in 2016 May. My observation from June 8, 2016 blog is reproduced below.

Pic

This year until May 18th when Venus and Mercury were free-wheeling together in the sky without any planet in direct opposition, it was raining copiously in many places.

Pic

Once they moved to Taurus and Gemini (Vaikasi and 1st fortnight of Aani), they came in direct opposition to Jupiter and Saturn.

Pic

Till the time one among them (Mercury) moved out of sight of the opposing planet Saturn there was no rainfall.

One can see a long term pattern in the movement of Saturn in particular. It stays in a sign for two and a half years. If that stay happens to be opposite to pre-monsoon months, pre-monsoon showers are affected. Presently it stays opposite to SWM arrival time. By next year it would be opposite to Aadi month when SWM must have spread throughout India. Rainfall at that time would be affected. Like this if we keep shifting the position of Saturn, it reaches Aries by NEM 2027 – opposite to Libra (Aippasi). For five years from then onwards the NEM would be affected (in general) but SWM could bring good rains depending on other planetary factors. Therefore Saturn’s transit does have an impact on marring rainfall prospects.

  1. Mars ahead of all planets scorches the earth.

Another confirmed planetary feature in my observations so far is the position of Mars ahead of all planets. If it is ahead there is excess heat and lack of rainfall. Such a scenario is depicted in the following diagram.

Pic

In the past between August 25, 2016 and July 29, 2017, Mars was having a long march ahead of all the planets. It was a hot and dry season with scanty rainfall throughout India.

The same feature existed this year till June 18th in SWM begin-time. There was a spurt in hot conditions until Mercury broke up the lead of Mars by crossing it on 18th June.

So we must watch out for Martian lead in rainfall months. This year Mars is once again racing ahead of all planets in Leo and gives a tough fight to Venus for a fortnight in late August. Fortunately Venus gets ahead and comes in close quarters to Mercury by 6th September. There is likely to be spurt in heat in the 2nd fortnight of August.

Ultimately only two periods (1) Mercury-Venus closeness and (2) Venus in western sky in October- November are going to give rainfall in the coming months.

Rainfall prospects between July- November

In the immediate future Budha-Shukra sameepyam has almost begun now with a separation of just 9 degrees between them at the time of writing this. The gap is fast closing with Mercury in retrogression.

On July 24- 25, Venus crosses Mercury and comes in front of Mercury. The crossing day marks a meteorological event. Venus in front of Mercury ensures copious rainfall. The closeness happening in Punarpoosam, East India and west coast would receive good rains. For general trend refer the following table already discussed in January 27th blog.

Pic

We can see a month-long gap between August 21st and September 20th. This means early end of SWM and early arrival of NEM. However with Mercury – Venus starting on 6th September it is NOT going to be a bad SWM. Some late revival of SWM would happen before the scenario shifts to NEM.

Rainfall scenario for Chennai based on Solar Garbottam

The solar Garbottam observation related rainfall period posted earlier in January 11, 2019 is reproduced below.

Pic

Rainfall scenario based on Daily Garbottam

Daily Garbottam observations sync with Solar Garbottam and Mercury- Venus closeness. Rainfall will occur on and off till October. Most precipitation would happen in October. After that a brief lull in November. Late December rains are also indicated.

Pic

PS-1: Sapta Nadi Chakra was found to be affect rainfall in the past years. Fortunately this year no planet is in adverse star of the Sapta Nadi Chakra. To know the Sapta Nadi Chakra click this link.

PS-2: The Garbottam must be the formation caused by sun’s heat, wind etc. The walking away of clyclones such as Pethai and Fani cannot be counted as Garbottam.

Rainfall reality check -1 (Feb – March 2019)

The first rainfall period of the year 2019 supported by planetary yogas began on 13th February. In my blog dated January 27, I had given all the probable periods of rainfall for the whole of India of which the earliest one starts on 13th February when the three planets Sun, Saturn and Mars start moving in alternating signs. The relevant part of that blog is reproduced below.

Pic

It is important to note that this transit is going to last for almost a month.

This combination in horoscopy design is given below.

Pic

This kind of transit was found to have caused floods and destruction in the past. Coming as it does in this part of the year, one can associate it with hail storms and flash floods causing unexpected damage to crops and life.

The location of rainfall is associated with the directions of the signs in which the planets are moving. It is seen that east and west are the directions indicated. To fine tune this further, we are looking at the stars in which the planets are transiting during this period.

Saturn > Purvashada  = Western division that encompass Ghats, Punjab, Haryana and Mleccha countries of the West.

Sun > Dhanishta, Satabhishak, Purva Bhadrapada = North West India and North India

Mars > Aswini, Bharani = North East India.

 

Combining all the directional inputs, we can say that North western parts of Western Ghats, North West India, North India and North East India are influenced by this transit.

Another notable point in the current transit is that both East and West are covered in the signs of the zodiac. When these two directions appear simultaneously in the past we have seen rainfall in both eastern and western sections of South India.

Now looking at another combination of rainfall yogas, the following was written on the same blog on 27th January.  During the same period of the above yoga, Mercury enters combustion and also begins retrogression – both associated with trigger to rainfall.

Pic

 

The above mentioned two combinations happening in the same period of Feb – March 2019, is likely to see good rainfall, but accompanied with destruction and cyclonic effect (thunder storms). We have started seeing weather portals reporting of rainfall in the regions indicated by astro-meteorology and expecting more to come in the coming days particularly on 16th Feb.

Meanwhile I have another interesting information to tell.

 

Cyclone Titli’s past-into-future impact

The concept of rainfall is that, it must have a link with the date 6 and a half months prior to that. With rainfall expected by weather experts in Maasi now (Feb – March), the corresponding month in the past happens to be Purattasi.

Interestingly two cyclones Titli and Luban were formed in Purattasi last on both sides of South India. We can find a correlation between the dates then and now, implying that the regions that experienced cloud movement but no rainfall then are likely to experience rainfall now.

Cyclone Titli

Genesis = Oct 6. > Waning Dwadasi

Intensification = Oct 9 > Amavasya

Landfall = Oct 11 (Andhra) > Waxing Tritiya

 

The corresponding dates now are

(Purattasi) Oct 6. > Waning Dwadasi = (Maasi – Waxing Dwadasi) Feb 16th – 17th 2019

(Purattasi) Oct 9 > Amavasya = (Maasi – Pournami) After midnight on Feb 18th and 19th

(Purattasi) Oct 11 > Waxing Tritiya = (Maasi -Waning Tritiya) Feb 21st – 22nd

 

Cyclone Luban also formed on the same date but drifted off India on the Arabian Sea. Only Titli could have left an impact on the Indian land mass.

Weather experts have predicted rains in south of Tamilnadu bordering the Western Ghats. If some rainfall activity is seen between 16th to 21st / 22nd February in the regions covered by the clouds of Titli, then it is definite proof of how Garbottam works.

Our data shows that 16th Feb would be a momentous day while the next day of heavy rainfall begins on 5th March when Mercury starts retrogression. The entire period between 13th Feb and 14th March would see rainfall activity in the directions mentioned above with some places experiencing flash floods and destruction.

Rainfall prediction for Cuddalore (2019)

As we are waiting for a good season of rainfall 2019, here are some Garbottam inputs by a resident of Cuddalore, Dr T.Vasudevan, MD, an Anaesthetist by profession. Impressed by the Garbottam articles, he wanted to try out for Cuddalore and had provided his observation right from Margazhi Garbottam onwards. His Daily Garbottam observation is also continuing, despite his tight schedule professionally. As far as this branch of knowledge is concerned we are all learners and his contribution is going to add to our knowledge. My heartfelt thanks to him.

Solar / Margazhi Garbottam for Cuddalore is disappointing, though the daily Garbottam is giving rays of hope. As of today rainfall dates are available till July only and they look promising for Cuddalore and Chennai as well. A comparison of the 2 places is also given at the end of this article. The Solar Garbottam dates become relevant only from 22nd June onwards. Until then and even after it begins, we need to rely on Daily Garbottam for day-to-day prediction. In my opinion gained so far, Solar Garbottam gives a kind of long range prediction while Daily Garbottam is needed for accuracy.

Solar Garbottam for Cuddalore

A marked revelation is that November 2019 is going to be dry for both Cuddalore and Chennai. (To know Solar Garbottam for Chennai, Click here)

 

Daily Garbotam for Cuddalore.

Pic 1(daily)

One will see the to and fro jumping of months of rainfall dates despite the fact the observation dates are sequential. This is because the lunar months get split within a solar month in such a way that a particular phase (waxing or waning) would appear only half in the beginning (followed by the next phase in complete) and then followed by the first half of the subsequent phase at the end of solar month. This happens in the years after the year of Adhik Maasa. (The last Adhik Masa occurred in 2018)

Rainfall is expected in the earlier phase in any month (as per our observation in the past). This is a momentous observation as it removes the confusion between solar and lunar calendars. This establishes that Time works along with solar calendar only, with lunar months aligned with solar months and not independently of solar months. The implication of this is that the zodiac is sidereal and all observations and predictions are relevant to sidereal positions only.

Now coming to the comparison between Chennai and Cuddalore, one can see close dates of rainfall between the two places. The table is based on the observation as until 12th February.

Its our wish that people from other regions also start watching the sky for Garbottam and and help us form a data base to know about the rainfall prospects well in advance. Read More »

Synchronising Daily Garbottam, Solar Garbottam & planetary yogas (Part 1 – till July 8th)

Observation of Daily Garbottam is essential for detailed assessment of rainfall prospects for everyday of the entire period of SWM and NEM. Ideally one must start daily observation from the month of Karthigai, for only then pre-monsoon rainfall prospects from Chithirai (April- may) can be gauged.

By the simple rule of rainfall coming in the 6th solar month from the month of Garbottam observation, we can say that if it rains in Karthigai, there will be no rains in Chitthirai. If it is cloudy in Karthigai and Margazhi, peak summer would be less hot as rains can be expected in Chithirai and Vaikasi – the period of Agni Nakshatra. This would have a chain effect on the 6th month from then onwards, with Purattasi and Aippasi coming 6th from Chithirai and Vaikasi. This means if it rains in Agni Nakshatra, there will be less rains in the beginning of NEM season.

This year’s scenario shows that there will be rains in Agni Nakshatra and consequently less rains in Aippasi (October).  With the data in our hand collected so far we see daily Garbottam supporting rains in May and Solar Garbottam showing lack of rains in October. But as we keep observing on a daily basis, we would know for sure whether October dryness is indicated in Daily observation also.

Added to these two (Daily and Solar Garbottam) are the planetary yogas we wrote down HERE. When all these three concur, rainfall is very much certain. This year I will be giving all these three in bunches of relevance to 2 months as and when Daily Garbottam is progressing.  This makes it easy to analyse the scenario and compare with real time rainfall. Any discrepancies with real time rainfall can be further analysed to fine-tune the predictive tools.

Given below is the Daily Garbottam observation which I started from December 28th 2018, the day Solar Garbottam started. Only rainfall expected dates are given along with the Garbottam details. The rainfall period given here  ranges from May 15th to July 8th of 2019, the period related to Daily Garbottam seen till today (27th Jan, 2019). Some interesting observations are written below the chart. The first column is the date of observation of Daily Garbottam

pic 1 daily garbottam

I included the overcast days of cyclone Phethai which went on for 2 days but split between 2 Solar months. The result is that rainfall months also were split. The first date in April is not supported by Planetary yogas. Solar Garbottam didn’t start and therefore is irrelevant for that date. If it rains on that date (April 26-27), it means Phethai clouds can be counted as Garbottam. In future, failed cyclones that pass off without rains can be counted for prediction of rainfall later.

The second date (May 27 – 28) comes within the period of Daily Garbottam.

As one scrolls down the data, one finds the rainfall dates suddenly changing by nearly a month for two consecutive Garbottam dates of Jan 1st and 2nd. This happens due to the piling up of days in lunar cycle. Every 3rd year, the lunar month more or less coincides with Solar month. After that every year the days are accruing in lunar month to such an extent that we find two similar phases in the same solar month – eg: few Tithis of waxing phase occurring in the beginning and end of the solar month.

In 2017 I was faced with the dilemma of which one to pick up. I found that it rained in the tithi of the phase coming in the beginning of the solar month. This year with same phases occurring twice in the same solar month, I have assigned the dates to the phase coming in the beginning of the month. As a result the reader will find May 15th coming after June 12th. If the rainfall pattern follows this, my observation can be taken as reliable. This year this period coincides with Agni Nakshatra period.

Till the last week of May, rainfall is indicated. After this, rainfall is indicated from June 8th onwards. The Garbottam date is same as Solar Garbottam date, but Solar Garbottam indicators start from June 22nd only. There is no planetary yoga for June rainfall in Chennai. If it rains, this is purely on the strength of Daily Rainfall.

The next important date comes on July 7th. This is supported by very good Garbottam in Daily Garbottam. This date is also supported by Solar Garbottam and planetary yoga of Mercury starting retrogression in the sign Cancer and crossing Mars backwards. By this Mars comes in the lead indicating heat aided rainfall (Veppa Chalanam). It could also mean a meteorological event happening.

Given below are the relevant parts of the Solar Garbottam chart for comparison with the Daily Garbottam chart given above

pic 2 solar garbottam

The chart below shows all the three, Daily, Solar Garbottam and planetary yogas.

As and when rainfall occurs, those dates will be incorporated for comparison and reproduced at the end of the year for assessing the reliability of prediction through these methods and also for learning and improvising.

pic 3 synchronised

All the three concur with the date starting from July 7th when Mercury starts retrogression. Whether this synchrony results in a meteorological event will add a new leaf to our understanding of astro-meteorology.

Checking Daily Garbottam is the most challenging exercise, as one has to be in station and be watchful of the sky. I record my thanks to @RainStorm_TN for helping me out whenever I was out of station. I also express my thanks to Dr Vasudevan, MD Anesthetist, of Cuddalore for having started Garbottam observation for his region to forecast rainfall in advance. His observations will be posted in another blog.

This is ancient wisdom, lost and forgotten but resurrected again now. With more people getting involved we can make this branch of knowledge vital, viable and helpful in rainfall- prediction.

Result of Solar / Margazhi Garbottam for Monsoon 2019.

Nearly a fortnight long observation of Margazhi Garbottam came to an end on 11th January at 1-13 PM. This year the Garbottam period was eventful and totally different from the past 3 years (relevant for monsoon 2016, 2017 & 2018) when spotless blue sky was staring down at us on most days. Except for 2 days corresponding to November 2019, all the other days had some signs to guarantee rains. This Garbottam being the first source of assessing the entire rainfall season, the mostly eventful Garbottam gives me a sigh of relief in the wake of a bad prediction of rainfall for the upcoming year ‘Vikari’. Keeping ‘Vikari’ year prediction for another day let me present here what I gathered from this Garbottam that is applicable to Chennai ONLY.

The first two days saw surging grey clouds from North East – North West, apparently from the sea. From my observation of similar events in the past Garbottams, this is not exactly how solar Garbottam has to happen. A similar kind of Garbottam gave rains in the sideline of a cyclone (Gaja) in the 2nd fortnight of November 2018. Interestingly this cloud surge indicates the dates of some planetary trigger when Mercury overtakes Mars and comes in the lead of all planets in a watery sign (Cancer) and Saturn and Ketu enter into deep conjunction. The dates happening to be July 5th to 9th sound improbable for rains from a system, but it could also result from convergence of winds (Mercury for winds) and ‘Veppa Chalanam’ (Mars behind Mercury). How this happens will be an addition to our knowledge of astro-meteorology. 

An important feature I noticed was the role of cold northerlies and fog helping in cloud formation after the sun climbs up the next day. When fog was much less, the next day had clear sky. When cold winds (Vaadai- Kaatru வாடைக் காற்று) were blowing, there was very good cloud build-up the next day causing them cross the sun often. When it was misty the previous night or next morning, the sky was misty white till noon after which it was blue sky only.

On 10th January (Day 13), there must have been some difference in the moisture level of overnight mist – as one could see the misty white sky developing clouds that caused good Garbottam in some places of Chennai, while it was not so in my place of observation. Similar formation was something not at all seen in the last 3 years after Chennai was flooded in 2015. This apparent disparity makes me think that 2019 is going to see far better levels of rainfall.

The most unique day was Day 10, on 7th January between 8 to 10:30 AM. The overnight foggy weather seemed to give rise to a peculiar cloud formation of neatly arranged bundles of clouds much closer to the surface – not like cirrus clouds seen high above. This was noticed at other parts of Chennai and is comparable with similar looking clouds noticed in south of South India from Chennai to Kerala on 27th February 2018. It resulted in the rainfall of the century to Kerala on the 195th day – on 8th August 2018.

day 10 - jan 7th compare with kerala clouds

Similar cloud formation seen on 27th Feb 2018 for comparison

 

Compared to Kerala cloud, the duration was much less in Chennai. But the planetary combination was unique like it was when similar formation occurred in Kerala. Mars, Mercury and Venus were in exact square on 27th Feb 2018, when that cloud formation was happening.

In Chennai Mars and Mercury were in exact square at the time of cloud formation. On the corresponding dates (Oct 25th and 26th, 2019), Mars comes out of combustion and Mercury enters combustion both are trigger factors for very good rainfall.

The Feb 27th Garbottam (Kerala) did not happen in Margazhi. So it was counted as ‘Daily Garbottam’ and the impact date was deduced based on the phase and tithi of the moon on the 6th month.

But in Chennai Garbottam this time, it is counted for Margazhi Garbottam and also Daily Garbottam. The above mentioned dates in October are deduced from Margazhi Garbottam. In Daily Garbottam, the corresponding date is 20th May, 2019. This is also an important date to watch for rainfall and the nature of rainfall.

This Margazhi Garbottam observation is relevant for the period starting from June 22nd. However other features are there to ensure early rainfall for Chennai. The same data of Solar Garbottam is relevant as Daily Garbottam observation and it will be written in another blog shortly.

The chart given below gives the observation and the probable dates of rainfall. One drawback of this observation is that night time sky could not be watched. So nearly a week – rather the alternating weeks are not covered in this. However it was found that it was not at all cloudy on any of the nights of Solar Garbottam, but one important feature was early morning fog on most days which was found missing in the previous 3 years of my observation of this Garbottam in Margazhi.
