                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Az  Vel Scale was 586.0 measured 583.1, 587.8; 585.4 no change
 Alt Vel Scale was -626.0 measured -626.2,-626.5;-626.3 no change
 Moderate seeing all night. Photometric until the last few hours
 of the night. At 04:15 (UT10:15) the Rotator Controller rebooted
 itself. Fritz had reverted back to an earlier version of the software
 in the afternoon. It this is a bug in the code it appears to be common
 to both versions. I was able to recover within 4 minutes however the
 error occured 6 minutes into an exposure. Therefore I counted 10 minutes
 lost.
 No other problems tonight.
