              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
The start of the night had a ToO program with DIS; then afterward it was
all echelle.  Mostly the night went smoothly except for one case where the
wrong position was centered (the observer knew she had pressed Center Sel,
but she was pretty sure she had not clicked on the position listed - this
occurred at 01:43:32 UT).  No time was lost to this, but I did puzzle over
it while we were doing other things.
There was also a cluster of ecam problems which required a slitty reboot
to fix.  Although it came up quickly and smoothly, I delayed attempting
the reboot as a last resort so we did lose a few minutes with no guiding
while I tried lesser solutions.
