                  ------------- ACTIVITY LOG --------------
 Observing Specialist: Noel Camron Hastings
 I opened tonight at 19:00 MST to begin cooling. All systems working
 well, but thick, high cirrus.
 We had an IRSC failure around 2am due to hard drives filling up. Although
 the hard drives were cleaned out a little to allow more images the
 software still seemed to be unhappy. We did not run IRSC after 3am.
 Clouds kept most of the data acquisition to a minimum. Moonlight in the
 cirrus made for a bright sky.
