Danjon Number Distributions


By Helio C. Vital


A very informative set of drawings has been made by REA`s experienced observer Alexandre Amorim. It clearly illustrates the evolution of the Moon`s brightness distribution during totality according to Danjon`s rating. The local time (UT-3 h) is provided for each picture. As expected, at mideclipse the Southeastern part of the disc was much dimmer than the Northwestern one, that was much closer to the umbral edge.
