                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Another humid night with several open then close moments. At the
 beginning of first half we were open for long enough to focus
 but slew to a traget field but not long enough to get any real
 data. The dewpoint did not drop again until second half when we
 were able to open for a few short hours. At the end of second
 half it looked again like we might get a chance to open however
 the skies had clouded over and shortly after I had decided it
 was not likely to clear the humidity creeped back to over the
 limit. I spent a great deal of the night assisting the DIS team
 and working collecting some post engineering data on the instrument.
