Last night was an interesting evening. At sunset it was nearly
completely clouded over. There was vast cloud-to-cloud lightning to
the East.
Since I am providing supporting photometric data for an
interferometry project at the US Naval Observatory in Flagstaff, I
wanted to get as much data during the week as I could. I turned on
all my equipment and went to play darts. When I came back the sky was
completely clear and indeed a photometric night. I was able to get
good photometric UBVJH data. So again while the evening probably
would not qualify as photometric for some, it was indeed photometric
for me.
