              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Clouds most of the night.
My 2nd half observer noted that her first 4 files did not automatically, the later files came thru fine, starting with her 5th red flat.
The skies started to clear a little before 4AM and we opened at 04:14.
