              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
Had to power-cycle the dataq box in the afternoon.
While it was windy during A-half, the telescope was pointed away from the wind and wasn't having any issues (aside from bad seeing) so we stayed open. Clouds came in during B-half and we closed up due to precipitation on radar nearby at 03:00. The clouds showed no promise for clearing up, so we called it a night around 04:15.
