Telescope and Camera Status (Alberto)
Everything OK. Ready to start dome flats. During the day they
have been doing some pumping on the LN2 vacuum lines, with significant improvement
at the cryocoolers.

The M and C-floor cooling hasn't been operating at full efficiency this season. That is being
improved. One temperature sensor, previously temporarily located on the C-floor,
was relocated to FNAL in mid-October. That analog sensor is noisy at times.
Digital Temperature sensors are being moved to the cooling coils themselves.

Last Night's Data (Marisa and Liz)
Last night backplane 5 didn't readout at the start during bias frames. So
that's a PanD role restart. Maybe we need Telops take a few vsub off bias frames
to check this. Liz put details in the elog.

One stuck shutter error required a reset and a reconfigure.

Lots of decent WF data last night.

Every 5 or 10 minutes we get a warning beep about more than 7 degrees separation.
Maybe check domeaz vs telescope az after a long slew. Kentools can pull up the

DESDM (Margaret)
There was a problem ingesting the files from last night into the database.
One file is still missing. Greg is looking into that.

11/5 and 11/6 are both close to being done with DQ ready tomorrow.
That should be very interesting.

Obstac has two tweaks:
EN noticed that we've been doing a lot of tiling 2.
It hasn't been configured to do Y when the seeing was good. A few sections
of tiling 2 Y are close to getting near setting. So it goes to 2 but then
because the seeing is good it hasn't done the Y. That needs to be fixed right now.
This is the first time the weather has been good-enough to notice this bug.
Then When the Moon either rises or sets Obstac changes filters. Eric wants Obstac
to be able to go to be able to change to a new tiling.
The new code is checked-in and needs to be tagged and installed, then a SISPI restart.
Eric will declare it while the calibs are going on and SISPI will get a restart
when observers get back from dinner.

Weather looks good right now. Clouds in the S, as was so last night.
Eric expects Obstac will start with tiling 2 and then move to tiling 3 when the moon sets.
SK reports he looks at
