                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Skies were mostly clear at sunset however I delayed opening because
 I was nervous about an approaching radar return. As soon as I confirmed
 it was going to pass south of us by more than 25 km (nearest lightning)
 I opened. Seeing was poor to moderate. Cloud cover was again bothersome
 and increased throughout the night until we were forced to give up on
 observations about 30 minutes before the start of twilght.
 No problems.
