              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
We had clouds all night and, while I thought we didn't have any chance of opening, we were able to stay open most of the night. The seeing was terrible, unfortunately. Around 3am radar appeared in the basin and we closed. We were not able to reopen.
No problems tonight.
