              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out mostly clear but there were thunderstorms to the south and west and virga to the north.  The western storm swung south and just missed us.  Unfortunately, the stuff from the NE did not miss us and we had to close at 23:08 (I knew that 0.68" was too good to be true!).  We were able to reopen at 00:02 and stay open the rest of the night but we were constantly having to fight through clouds.
