                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Dembicky
 (The first half night log was lost so this is what I could recall from
 memory)
 Started the cooling fans around 18:00.  Opened the enclosure/telescope
 at 18:45 under cirrus skies.
 We focused the telescope at 19:25 under 0.66 arc sec seeing with GrIm in
 K'.
 2nd Half Observing Specialist: R.McMillan
 The first half observer had little luck with GRIM, but there was some
 thinning of the clouds at midnight and we had hopes for the DIS
 program.  We were able to focus and get set up on the first target,
 but the clouds thickened just a few minutes into the first exposure
 and we closed soon afterward.
 The sky began to clear after 05:30, leaving just barely enough time
 to get some useful spectra for the final program.
