              ------------- ACTIVITY LOG --------------
Observing Specialist: N.Ule
Had nice clear skies all night.
DIS initially needed to be focused at 650 but as the night progressed the
value was lowered (see focus log), something to keep an eye on for future
nights.
When rotating the tertiary from NA2 to NA1 the Spicam Ion pump stopped
responding (may be unrelated).  Bill's instructions for this (from my end)
was to power cycle the ion pump by unplugging it and starting it up again.
 I believe there was more to it than that but I was not involved with any
additional steps.
