Camera and Telescope
All OK. Restarted sispi w/o problems. On the white spot, ready to begin calibs.

Last Night's Data
Liz saw 4 condors yesterday afternoon after it cleared up.

Evening started with snow and sleet. Couldn't do calibrations until
7:30 PM, SS were about 10 minutes late, setting back the start of observing
by 9 minutes. Probably if it were any later they should have skipped dome flats
and simply done those in the morning.

Obstac has worked smoothly.

Seeing started at 2" and got better all night. SN at first and WF by the
end of the evening. 1" seeing at the end. Happy to get anything at all.

M. believes they got all the data. Processing not started.

We are hoping to apply the filter-dependent DQ cuts independent of the transparency
because the filter-dependent stuff is ready to go. But there might be a problem
because if the catalog-matching stuff that performs the transparency fails, then
the data would be bad.

-> Margaret et al. keeps doing DQ as before until the new code is checked.

There was a question in SN telecon today. On 11/9 there was crap SN data because of
poor seeing. This isn't propogated in the DQ code. Steve K. will check the seeing
projected-to-i-band-projected-to-zenith is worse than 2" using kentools. If so
we'll declare exposures bad for the short exposures invoking the ad-hoc protocal
available to OPs. We'll look at the dep exposures on an exposure to exposure basis.
No SN field is at more than 4 days latency at this time.

-> Plan to enter this SN DQ for tomorrow night with Eric's help.

For Tonight
Clear conditions. Let's hope for good seeing.
Probably WF if the conditions are good-enough with early Moon.
