              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Gcam failed around 04:46
We had problems guiding with DIS on the DD03 program.  Guider offsets didn't seem to move the field much.  example, to move the star about 0.5 arc sec I needed to issue about a 3 arc sec offset.  The field also wanted to drift to the left.  This was along the alt axis.  I did an MS.DUMP at 07:56:16.  The alt error from the DATAQ was -1.35.  It seems I had this same problem last month as well.  We choose another guide star and that seemed to help (or we may just moved westward from the transit?).  Tracking seemed better the remainder of the night (we stayed on one object).
I checked the tape mark on the NA2 rotator at the end of the night and it wasn't off by much, so I don't think it was the NA2 rotator being off.
