                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 During the first half a couple DIS slit images were messed up (blank with odd patterns).  The
observer was sub-framing (don't know if that really matters), when I took a full frame exposure
it cleared up on its own.  We didn't have any other problems the rest of the night, even
sub-framed.  Sorry I didn't record what the slit frames were, but it was visually obvious.  It
happened at 04:17UT from the message log so finding the correct slit images should be pretty
easy.
 Since the first program ended a few mins ahead of schedule, I gave the GFP folks a few minutes to
install some filters in the GFP so they could do further checkout during the 2nd half tonight.
 DIS blue ion pump running a bit high when I closed in the morning.
