              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
A nice thunderstorm rolled through this afternoon and into the evening. And then just sorta kept building and rolling off of us for the rest of the night. We had lingering clouds and radar around us but not on top of us for most of the night, which was very frustrating. As soon as it looked like it would be clear and new wave of clouds would come off the Organs. We were not able to open :(
No problems tonight. Except that there are more moths.
