                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Very poor seeing at the start of the night then the clouds rolled in
 shortly after we focused. Around 0300, there was enough of a break
 in the cloud cover that we tried again. Seeing had also greatly improved.
 No problems.
