                ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage, J.Huehnerhoff
Some thunderstorms around again in the early evening. Then skies mostly cleared.
Problems with SPIcam:
First symptom, spicam filter wheel would not change filters (after it had been
working fine for cals). I tried homing it, reconfig, and then went up into the dome
took it out, put it back in; home, and init. Worked again for a little bit. Then
Expose would not work. Restarted nubs, init, restarted icc. Then icc would not
connect.
Fritz advised the spicam electronics needed to be reset on the instrument. This
needed to be done multiple times. The spicam camera would come up, and then it would
try
to init the filter wheel.  The filter wheel would time out, and then communications
are lost again, only brought back by a reset. Then when we would return to science
it would all happen again.
The rotator was at -128. We tried 180 degrees from there since it seemed to be happy
at 0. This position seemed to work better. SO then we decided to try to avoid that
rotator area around -128. Various error messages were streaming out. These I
reported in the PR, which was an addition to PR #808.
Apollo was still having hardware problems and therefore gave their time to PU01.
