                              ACTIVITY LOG
(* means a trouble report has been issued or appended to)
1st-Half Observing specialist: Deglman
The telescope was opened a bit late (17:50) due to high winds.  Partly
cloudy most of first half.
2nd-Half Observing Specialist: McMillan
Second half showed light cirrus, but nothing heavy enough to prevent
observations.  Internet outages at Johns Hopkins necessitated about an
hour of service observing, since the remote observers couldn't get
their Mac to connect to dryrot by modem.  A later, shorter outage
caused the loss of a ten-minute exposure.  Image motion was seen only
once, but unfortunately the LVDT monitor had disconnected, so I
couldn't check to see if there was an variation.
