McMillan Note: Tonight and last night, JH01 swapped some of their time with UC03 to get a more accurate window around the eclipses. High dust counts kept us closed for the first portion of the night; once we were able to open, the telescope was quite warm and the seeing notably poor. After a few hours, the seeing improved to moderate, and the morning hours were quite productive, including apparently successful observations of an eclipsed Jovian moon.
