              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
He had a few issues with agile tonight. First, the heartbeat needed to be reset at checkout. Once we were on sky, the rotator really struggled near rotation -110 and we got multiple rotation errors:
-122.6 (01:37)
-112.7 (04:16)
-110.3 (04:50)
-109.7 (05:45)
The weather was a bust for A half. There were clouds and radar returns but nothing actually seemed to hit the ground. It was a bit touch and go for all of B half but we only had to close for 1.6 hrs when a wave of precipitation came our way. Seeing was not good.
