              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening was clear with poor seeing. Oscillations in altitude occured around 21:20, was quickly resolved by slewing under target and coming back to it from below. Seeing improved after 22:00.
At 03:07 we had another problem, different it seems. Altitude was not able to track dowards fast enough. Current was pinned near -10 amps. PR has been sent. Was resolved by 03:14. We were open all night.
