Quick summary of our astronomy findings for AV observation are as follows:
(1) An astronomer was capable of noting down ‘Arundhati walking ahead of Vasistha’, with a naked eye, at the time of my proposed (and originally and previously proposed date for the 18 days of Mahabharata War by Dr. P V Vartak) year – 5561 BCE for the Mahabharata War.
(2) The maximum separation between Arundhati and Vasistha (with Arundhati ahead of Vasistha) was about 500 arc-sec (8 arc-min). Although, this separation (with A ahead of V) began as far back as 11091 BCE, it was gradual and only became pronounced around the time of Mahabharata War. If we assume only naked eye resolution (and observation) which is around 1 arc-min, one can say that astronomers (visual observers) would have noticed Arundhati walking ahead of Vasistha only some time (few centuries) before the year of Mahabharata War – 5561 BCE.
(3) “Omen lists” employed by Vyasa, that appear multiple times within the Mahabharata text is a mixture of ordinary (positions and phases of the moon, analogies of the planets and nakshatras, position of the Sun) astronomy observations and not so ordinary astronomy observations (AV observation, eclipses, Vakri motions of planets, eclipses, etc.).
These ‘Omen lists’ also included, besides astronomy observations, fantastic and trivial or meaningless (sounding) descriptions.

Implications of the validation/corroboration of AV observation (based on my theory of Visual astronomy observation) are as follows:
(1) AV observation provided great illustration of how a theory is corroborated that also results in growth of knowledge.
(2) Growth of knowledge came in the form of a time interval (mind you – a unique time interval of 6500 years) bounded on both sides (11091 BCE and 4508 BCE) for the plausible year of Mahabharata War.
(3) Scientific and rational minds like (nay love) such stuff – mentioned in (1) and (2). Even those familiar with other Indian methods of corroboration – Pratyaksha, Shabda, Anumana; AV observation provided excellent illustration of the validation of Shabda Pramana (verbal testimony) corroborated by Pratyaksha Pramana (empirical proof) .
(4) Time interval due to AV observation provided decisive falsification for any proposed year of Mahabharata War that falls after 4508 BCE (and before 11091 BCE).
(5) Since Mahabharata text contains numerous astronomy observations, which in turn can contradict time interval proposed by AV observation, My theory became a daring theory, a theory with very high degree of testability and for that very reason, a theory with very high degree of falsifiability. Scientific and rational minds should be joyous with the stuff of this kind.
Thus, AV observation provided much to our understanding of not only the timing of Mahabharata War, but much insights into the extent of sophistication in astronomy of Mahabharata times.
But let’s not forget that AV observation was part of the list of Omens. And by definition of Omens (to employ definition of Omens as asserted by Shri Shrikant Talageri and/or Dr. Elst),
This would mean, AV observation was a rare and not so ordinary phenomenon to someone (Vyasa) noting it down among a list of Omens. Assuming this definition of Omen, can we explain the context of AV observation?
We surely can!
That would be the subject of my next post (in this series).
