Hi moondialists: Here are the results of my observations during the January 20 total lunar eclipse. We had excellent viewing conditions with low ambient light pollution.
Readability: The gnomon's shadow disappeared when about 3/4 of the moon was darkened. Time accuracy: The sundial kept perfect time in the moments just before the gnomon's shadow disappeared and just after it reappeared. (I corrected for EOT and longitude). Declination/date readings: As some of us suspected, the date showed July 20th throughout the course of the evening. Color: the moon during totality was a yellowish ocher, and had a very three dimensional look. Just before the last sliver of white lunar surface disappeared, the moon looked very much like a picture of Mars with it's white polar cap! John Carmichael Tucson Az
