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.
