 Observing Specialist: J.Dembicky
 Happy New Year!!!
 AZ velocity scale measured: 580.0  was: 577.0 changed: 580.0
 Alt velicity scale measured: -604.1 was: -603.0 changed: -604.0
 I noticed that on the Dataq, the Rotator Command voltage and the Altitue motor current plots look
very similiar (same bumps and glitches at same times).  Are these reading the correct items?
 The DISslit images (bright stars) had vertical streaks above them.  Perhaps the shutter is stuck
open?  Really bright stars had a bright streak above and a dimmer streak below (the dimmer
vertical streak is expected for really bright stars as they saturate the CCD but the bright
streak on one side isn't.)
  See disslit image 328 for an example tonight.  PR 918 appended.
Not telescope problems.
