                ------------- ACTIVITY LOG --------------
Observing Specialist: G.Saurage
Local radar activity kept us closed for the early part of the night. Since
the weather was moving in from the East, the radar somewhat untrustworthy.
It seemed to be clearing after midnight. I opened at 12:40 with wispy
cirrus here and there, but a clear radar. At 5:15am we closed since
humidity was over 85% and winds were hovering around the limit.
Apparently, DIS ICC lost connection. It was not on tonight but Jon
Brinkmann was getting emails about it, and tcc could not connect. I logged
into the icc and issued a dis start, restarted the nub, did an init and
all seemed fine.
The NA2 guider “works” in as much as it will take images, but the images
are not normal. They seem to have a residual light/dark triangle pattern
that does not clear with a restart of connections or power cycle.
All TUI’s crashed about 03:20am (my on-site observer’s as well as my own).
I repeatedly tried to connect, getting an error saying “connection
refused”. Called Fritz Stauffer and he discovered the file system on 35m
was filled up. He quickly resolved the issue and we got back online in
about 20 minutes.
NIC-FPS was left mounted for 1st-half observers tonight.
