              ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage
Clear skies all night. Heavy smoke smell in the air at sunset. Dissipated over the
next hour or so with a shift in wind direction. Moderate seeing.
After operating fine for 4-5 slews the agile rotator pin managed to slip back into
place causing a rotator Motion Error. I pulled it out again and tried to fasten it
more securely.
At 3:00 we discovered turning on the truss lamps from TUI did not actually turn them
on, although there were no errors. I could not log into the lampswitch web page.
Called Fritz. He sent commands through the hub directly and the lamps still did not
turn on. He then restarted the lamps daemon. That worked. I've updated the wiki
pages to include his troubleshooting solution.
