              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
I had trouble configuring the DIS gratings for UW03, so UC01 had to wait
on me to start cals. Russet helped me figure out the gratings- the
vertical down shift in the spectra was not something I could fix in a
reasonable amount of time, so we let it stand. UC01's cals ran past his
start time, although we were open and cooling. We did not get on sky until
21:00.
I was unsure how to log this loos, because Sean was taking data, but I
ultimately decided on equipment time, because the gratings were not
cooperating during set-up, and I ran over my time. I did not list it in
the failure log- it was only my misunderstanding of the setup and not the
actual eqiupment that was malfunctioning.
[Changed from Equip time  to Obs time, since this isn't an equipement failure. - JMD per WK]
Counts for Bright quartz were low while on sky. I couldn't find a
justifiable answer, but it's possible that she was comparing open counts
to closed counts, but other than that, there were no more problems.
