                  ------------- ACTIVITY LOG --------------
 1st half Observing Specialist: J.Barentine
 We opened at 18:30 after the observers took cals.  Skies were somewhat
cirrussy; non-photometric but still useable.  That degraded rapidly after
sunset.  By 19:45 the sky was mostly cloudy and Iskra decided to abort the
current DIS exposure.  It remained cloudy for the rest of the half.
 2nd half Observing Specialist: R.McMillan
 Continued heavy clouds during second half.
