Almost clear, but with occasional thin cirrus lit by a moon 
two days from full, and some very bad seeing, especialy
early in the night. Productive night in any case, though
struggled at times.

Beautiful in the few minutes between moonrise and twilight -
spectacular conjunction of Venus and Jupiter, and 
could see the zodiacal light on the eastern horizon. 

See trouble report for glitches.
