                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky, B.Ketzeback
 Training Bill K. again tonight on 3.5m operations.  We had a minor
 problem with GrIm during checkout but resetting the electronics a couple
 times fixed it (I was dropping one quad of the image).  I opened the
 enclosure around 19:00 and turned the instrument over to tonights
 observers at 19:50.
 I was going to try and grab a quick S-H image (or two) but it seems the
 S-H machine went down and Craig had just left the facility about 10 mins
 prior (he would have been on the road so I couldn't have contacted him
 via phone).
 We focused GrIm around 20:10 with EXCELLENT seeing.  0.54 arc sec in J!!!
