              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Numerous problems with the Echelle slitviewer tonight.  I believe related to PR1274.  Private
email sent to Fritz with more information.  Just repeating the Echelle exposure seemed to fix it.
The Echelle guider would also randomly quit while guiding, several times tonight.  Simply
restarting it seemed to fix the problem.  The focus script seemed unusable tonight after this
problem occurred, although I could manually take individual slit viewer exposures.  The focus
script worked earlier in the evening but would not work once I started getting errors.
I also got some other strange errors at the end of the night when switching back to TSPEC. I think
gcam related.  Since I wasn't using gcam the error didn't affect me, but gcam would not work with
this error.  Restarting gcam fixed problem.
