UT 19:50 = LST 11:36
times in UT
slit 0.35" (Pos 0.711)
slit 1" (Pos 0.590)
rather good seeing in the beginning of the night (0.6-0.7")
goes up to 1.1" during the last two hours, 1.6" after twilight
clouds during the second half of the night
technical tests:
UT 19:51 #1-#8, R=5s, Bin 1/1, 1/1, Slow, RedMilkyFlats, Quarz lamp on (no B), only 1200 counts and there seems to be some orders missing
