              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had a lovely clear night with very good seeing at the beginning (I measured 0.91 arcsec, but it didn't log successfully), then mediocre seeing in the middle of the night, and then moderately good seeing during second half.  ARCTIC had several problems with the shutter getting stuck closed - I couldn't quite find a pattern to when the problem occurred.  The first case took me a while to figure out what was happening, but the later ones were pretty quick fixes.  There was also a NICFPS readout problem which just needed a quick init to fix it.
