Day 2 of Garbottam 2016-17 started around 10-20 PM on 29th December and ended around 10.50 PM on 30th December.
The impact would be felt between 5th July 2017 and 19th July 2017.
(1) Wind:- Cool breeze blowing from North east and East till noon
(2) Rain:- Nil.
(3) Lightening:- Nil.
(4) Thunder:- Nil.
(5) Clouds:- Cloudless during night. From morning onwards, white sheet of clouds were seen surging from east. By 8 AM bunches of them were visible with definite contours and were seen to cross the Sun. Cloud cover was seen throughout the eastern sky. They grew grey in colour as day progressed.
Between 8 and 8-30 AM bunches of clouds started crossing the Sun.
By 9-30 AM the sun light dimmed as sheets of clouds were hiding the Sun very often.
By 10 AM there was good coverage of the clouds that continued to hide the sun. This lasted till 12-45 PM.
An important feature is that Moon was in Purvashada till 10 AM. When Moon entered Uttrashada, the thickness of the clouds increased and dark clouds were constantly hiding the sun.
One can say that this is a good Garbottam that lasted for quarter duration of a day equal to 3 to 4 days in the middle of the fortnight in the impact period. This day’s Garbottam is comparable to the 3rd Day Garbottam of 2015-16 season which did fetch rainfall on the impact dates in July 2016. However the sky was completely overcast at that time with more greyish tint.
But today (2nd day) the clouds surged as a white diffused sheet from the east and as they traveled towards west they crossed the Sun. By noon the clouds near the sun look scorched and distant ones seemed to drift in mal-formed aquatic shaped such as swan, fish and tortoises.
(1) Terrestrial :- Behaviour of birds and cows satisfactory.
(2) Atmospheric :- (1) gentle breeze was there till noon whenever the sun was hidden. (2) Sun was crossed by dark clouds often from 9-30 AM till noon. (3) Aquatic shaped clouds were very less but many huge bunches of clouds with bumpy back were seen, some of them changing into malformed aquatic shapes. (4) Wind direction was from the North and east.
(3) Planetary:- (1) Stars appeared faint. Venus a prominent planet in the western sky looked dim and surrounded with a halo. (2) All planets were in Southern declinations.
Impact dates between 5th July 2017 and 19th July 2017.
Two hours of the Garbottam roughly equals to one day in the rainfall impact period. As such the cloud and breeze seen today in the 3rd quarter of the Garbottam day could impact 3 to 4 days in the middle of the fortnight of 5th and 19th July 2017. Probable dates are 10th, 11th, 12th and 13th July that could see moderate rainfall.
Rainfall supporting features during impact period.
(1) There is no proper combination of planets to support rainfall in the impact period. Only one feature, namely location of Venus and Mercury in the western sky exists. But they are far away from each other at more than 45 degrees at that time. This does not support rainfall.
There are Rainfall spoiling features of this period.
(1) Mars is ahead of Sun and all the planets. Sun is too close behind Mars. This combination is supposed to scorch the land.
(2)Venus comes in opposition to Saturn between June 29th and July 26th 2017.
(3The gap between Mercury and Venus starts at 50 degrees in the beginning of the fortnight and comes down to 35 degrees at the end of the fortnight. This gap is too big to support rainfall.
Inference :- Between 10th and 13th July 2017, there exists a probability for moderate to heavy rainfall in my place of observation and in many parts of Chennai. However the presence of Sun behind Mars and Mars in front of all planets is a strong spoiler. Rain clouds may gather on these dates and fail to produce rainfall.
