                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Started cooling fans around 18:00 and opened around 19:25.
 The guider ICC MAC locked up on us during first half.  A power
 down/reboot took care of the problem.  No observing time was lost.
 The 2nd half observer noted the "mystery" stripe in image
 henn_031001.0001r tonight.
 Otherwise we had a fairly quite night.  I adjusted the focus using the
 NA2 guider thru the night.  Seeing was mostly around 1 arc sec, with the
 occasional rise higher.
