                ------------- ACTIVITY LOG --------------
 Observing Specialists: B.Ketzeback
 Mostly overcast skies this evening with rain showers the beginning of
 of the night and ending with fog and high humidity second half. We
 opened for about 40 minutes after midnight when cloud cover had thinned
 and the telescope was still much warmer than the dewpoint. We did close
 when the dewpoint split dropped to the closure limits. About 10 minutes
 later the fog had settled in for the remainder of the night.
 J.Holtzman spent much of first half characterizing the new DIS gratings
 throughputs and I performed grating swaps. I also spent time tonight
 working on a programing project.
