              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had a hole at the beginning of the night which didn't last for long, but the observer was able to get a few spectra of bright targets before the clouds moved in and radar menaced us.  Second half the radar returns didn't look real anymore, but I hesitated over whether the clouds were thin enough.  By the time I re-opened the clouds got thicker.  I was able to focus but we didn't even try any science exposures, so I counted all that time as lost.  Sprinkles began just as I closed the dome.
I had trouble with the mirror covers failing to open at high altitude, but they succeeded on retry.
