                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J. Dembicky
Started cooling the enclosure (fans and louvers) at 16:50. Opened the
enclosure/mirror covers at 18:10.
The folks at UW decided to change their IP address tonight and suddenly
Remark didn't work (Gee, what a suprise!!!).  Craig had just left about 20
mins prior to this so I had them run the telescope from the command line
on the MC until Craig told me how to authorize their new IP address.
The seeing degraded around 10:20 and was very variable and dependant on
where the telescope was pointing.  We re-checked focus at 23:30 (both
instrument and guider) and found it to be around 1.2 arc sec.  On the next
slew the guider was back around 2-3 arc sec (but they were 27 deg off the
horizon in the E too).
Other than the UW people changing their IP address mid-stream, things ran
smoothly for the first half of the night.
 2nd Half Observing Specialist: Russet McMillan
 Second half was characterized by clear skies, poor seeing (1.2-3
 arcsec), gusty winds, and no problems whatsoever.
