Discussion on Blue Moon on 13th June, 2007 at Sion Unit

Well, this wed we continued with same discussion on Blue Moon. I actually sought for correct definition for Blue Moon.

And the correct definition is like this :
"Usually there are 3 full moons in every season. Sometimes, though it might happen that there come 4 full moons in one season. In that case, the third full moon out of those four full moons will be regarded as a Blue Moon"

So we see that, the definition stated by an amateur astronomer James Hugh Pruett as Blue Moon is 2nd Full moon occurring in the same calendar month(Sky & Telescope article, 1946) is Wrong!

Well,it was in 1999, when Phillips Hiscock corrected the mistake made by Pruett, in his article published in May 1999, Pg. No. 36-38.

But the actual credit goes to a group of 3 journalists...Roger W. Sinnott,Donald W. Olson & Richard Tresch Fienberg who were the first ones to take an objection to the old definition! Also they were the ones who found out how exactly the blue moon dates can be calculated, something which Pruett failed at!

After we were done with this discussion, Aniket took over and gave few questions to be solved by next wed.
