 Observing Specialist: J.Dembicky
 00:27:52 Issued a mount coordinate slew and rotation from TUI and the rotation did not work (-45
to +45)but the Slew did.  I re-tried command at 00:28:45 and it worked this time.
Alt Velocity scale measured: -626.3 was: -620.0  change to: -623.0
Az  Velocity scale measured:  576.5 was:  581.0 changed to:  578.0

I was having problems with my xterm windows closing on me (crashing? and closing all the xterm
windows).  It seemed to occur using IRAF once when I did an 'imexam' and once when I did a 'ls
-ltr'.  It would close all xterm windows on Obs1.
No instrument or telescope problems.
