               ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
High clouds throughout first half, thinner for a few hours after
midnight and then getting worse again.  Seeing was good but somewhat
variable during first half, better second half.
Fritz was in during the afternoon working on the DIS problem; he got
the red channel working by swapping out an interface card.
Everything seemed normal with DIS after that.
I checked out Agile and confirmed normal communications with the
instrument.
We saw some tracking imperfections during high transits (81-83 deg)
in both the north and south, but nothing excessive; this is always a
hard part of the sky to track accurately, so observers should use
caution for high objects.  We also saw some windshake in the west,
but again nothing beyond what would be expected.
During second half, the DIS slitviewer started displaying all zeros.
I restarted the dcamera and dcam nubs, did a dcam init, and that
cleared it up.  Only about two minutes of cloudy time were lost so I
didn't log it.
