                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Local storms and thick clouds subsided by 21:30 tonight and I was able to
 open but except for about an hour it remained mostly cloudy all night.
 The guider remainder unusable again tonight due to an unknown problem with
 the guider mechanism. It is clear that the stage is moving since the size
 of out of focus donuts does change however the mechanism reaches a limit
 before stars can be brought in focus. The stage also doesnt appear to home
 properly. The observer had to guide off the slitviewer all night. No other
 problems tonight.
