                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Had an LTA5 error tonight, apparently the rotator crashed.  Powercycled UPS stip per Fritz notes.
 That fixed the problem.
Az 577.8  580.0  579.0
Alt -637.9 -636.0 -637.0
During our first slew the rotator failed to move.  This time no error was reported it just
wouldn't move.  Called Fritz, left message.  I powercycled the rotator UPS line again (and this
time did a set.position 0.0, which might have been the problem earlier).
No telescope problems the rest of the night.
