The telescope was open tonight at 21:10.  I had to cycle the power to DIS
because the biases I was taking seemed to have the strange structural
appearance of two weeks ago when Charles Hoopes encountered a problem(5/5/98).
This seemed to fix it and Paula Szkody was able to start on time.
Comments:Everything went well for two hours until the clouds came in.
Obtained the spectra I needed for the objects being done with ROSAT but could
not complete a radial velocity study.
Bernhard Beck and Scott Anderson were available for the second half of the
evening. Comments:SPICAM worked fine.  Although the dome was open,
relatively thick clouds precluded useful data except for the first 15 minutes
of time slot.
