              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
TSPEC took almost an hour to fill tonight for some reason.  Amanda filled it last night at 18:30 and I filled it at 20:15 tonight, so just a little over 24hrs, which is sorta normal.  No issues with the internal temps so it wasn't out of LN2.  We opened and cooled while I was filling so Russet could get on with collimation.
Once things were filled, Russet did collimation.  I adjusted one hard point for her and then she did the rest with the Shack-harmann.
After collimation we slewed to a pointing ref star to adjust pointing model at NA2, checked several reference stars, and then checked at NA1.
We closed at 00:00 as radar was showing an approaching system.  It started raining around 03:20.  I was in the dome and in the middle of resetting the dropped quad on ARCTIC.  Dropped quad successfully recovered.
