                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
AZ velocity scale measured 579.3 was 580.0 changed n/c
Alt velocity scale measured -637.6 was -636.0 changed n/c
No problems tonight other than very poor seeing conditions.  The night started out with 2+ arc sec
seeing and got worse thru the night to over 4 arc sec seeing.  Seeing was also very variable which
made using the autofocus script near impossible.
I reset the rotator for Fritz at the midnight changeover.
