                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Az Velocity Scale was 573.0 measured 576.6, 580.6; 578.6 changed to 578
 We fought with scattered to broken clouds most of the night, just a
 few hours of which were mostly clear skies. There was one occurance
 of the slitviewer locking up and requiring a restart of tcamera and
 tcam. Recovery was fast and no time was lost. Otherwise everything
 worked as expected under the marginal weather conditions. At 05:00
 clouds became to thick to guide with the scheduled instrument and
 the observer called it a night. I was able however to use the last
 hour (mostly twilight) to mount, adjust the mechanical focus position
 and align fastcam at MB3 (aka TR3) port. I ran out of time for an
 instrument block due to cloud cover.
