                ------------- ACTIVITY LOG --------------
 Observing Specialist: W.Ketzeback
 Scattered to broken cloud cover at sunset and then increasingly
 clearing skies as the night progressed. Seeing was moderate to
 good in the near IR first half and moderate in the optical the
 rest of the night.
 During my afternoon checkout of the instruments I dicovered a
 problem with the echelle. It turned out that one of the RAID
 disks on the icc computer had failed. Jon Brinkmann spent many
 hours past midnight bringing the instrument back to life. I was
 able to verify return of communications to the echelle and the
 echelle motor controller during second half.
 No other problems tonight.
