Shri Oak has identified a period in the past when Arundhati was walking ahead of Vasishtha as described by Vyasa. This is based on the Right Ascension differential as obtained from software (which I presume itself based on observations and mathematics and algorithms). We can assume these data to be correct.
As we see today, the difference between the declinations of A and V is very small. That makes it difficult to decide who is ahead, to a naked eye observer. If you see any sky photo, it will bring out the position. We have to enlarge the photo before we notice with naked eye, Arundhati, distinct from Vasishtha
It would be interesting to know what were the declination figures for Arundhati and Vasishtha at 1)start of the ‘epoch’, 2) at the time Arundhati was Max. ahead of Vasishtha 3) at end of the ‘epoch’ and 4) today when Arundhathi is still significantly behind Vasistha (after being much behind earlier). This will enable one to judge (of course qualitatively speaking) the ability of a naked eye observer to assert that Arundhati was ahead at the Mahabharata war time.
I invite Shri. Oak to let us know the declination figures which, I suppose will be easily available. Any other reader with access to suitable software is also invited to do it.
