Notes from the 4PM Meeting and Additional Comments:

Run manager's Meeting Nov. 09, 2013
Eric, Marisa, Tom, Alberto, Don, maybe others

Telescope and Camera
The telescope is OK. On white spot. A tour is coming through right now.
After they do, calibs.
During the morning, more pumping on the LN2 lines. This
time on the LN2 return line.

Last Night's Data (Marisa)
WF but the seeing was not quite as good as the past couple nights.
All of Eric's Obstac changes worked as expected.

Checks of data when dome minus telescope > 6 degrees. The alarm
is going off a bit before the exposure starts, but by the time the
exposure is taken the dome readback seems to indicate that it is caught up.
No significant occlusions seen on the donut images.
Displays on the observer2 machine seem to be very slow. Will complain to TELOPS.

Assessments in hand this morning for 11/5 and 11/6.

On next Friday DESDM is going to physically move
the systems that catch data. So you want to make sure the data gets
to NCSA as fast as possible on next Friday.

Weather is looking OK.

Obstac is predicted to do tiling 1 and 3 in z-band, mostly.

Probably no meeting tomorrow. Check in the morning.
Possibility for SN to occur tomorrow night depending on the seeing.
