              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We delayed opening tonight due to clouds and potential precipitation.  I saw virga to the NE when I was up on the catwalk during checkout and the rain sensor went off around 19:30.  We had clouds moving up from the S that basically thwarted APOLLO observations, and the potential threat of rain.
We finally opened around 03:45 with no telescope issues to report.
Telescope parked at 104,70 in case of rain.
