                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 A few instrument problems tonight. We had reoccuring problems with
 both the A to D card for the camera and a problem which prevented
 the cal mirror from registering when moved into the beam. The AtoD
 problem prevented observations for about an hour, however we were
 also closed for a portion of that time for high humidity and
 excessively elevated 0.3um dust levels. The fear was the dust was
 smoke particulate from nearby forestry control burn sites. We closed
 at 18:50 and re-opened at 19:50. Seeing was great to moderate. No
 other problems to report.
