              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
I misread the work schedule tonight, which caused me to come in late.  Luckily our
observer noticed and called Russet, who called me, and then Candace.  Candace had
just made it down the mountain to Alamogordo and turned around to cover for me until
I arrived.  Russet did instrument checks from home.  It was cloudy so no onsky time
was lost.  Thank you Candace and Russet and Sarah for notifying us.
The clouds parted around 01:15 and I felt it was safe enough to open around 01:45.
We remained open for the remainder of the night with no problems.  Wind was out of
the East so seeing was poor.  It improved a little after 3AM from around 2.4 to
about 1.5 arc sec.
