Camera and Telescope
Everything is OK. Some work going on in the dome regarding telescope balance.
Calibrations after that.

Last Night
Partially cloudy for the 1st couple hours. Later on the sky
cleared and there was a lot of SN data. Finally WF Y-band, especially.

General impression for SN DQ is OK, but X1 i- and z-band have low signal to
noise but good PSF. X1 was first when it was most cloudy.
Comparison with Steve and some more results. Things maybe get better later.
C2 might be bad as well, as it was the second one.

There was a problem with the 1st standard field - TELOPs said the
airmass was too high. Let's see if we run into this again.

Yesterday they did calibration was done twice because of a hardware shutter failure
during the sequence.

We were surprised that it did C1 last night, it had been done the night before.
Later, Eric thinks SN desperation tactician did it, first time condition 5
turned true. Bright Moon and bad seeing and Y-band close to done.

They got the data from Last Night and are ready to start processing.
For Tonight
Weather is looking cloudy - like it did at this time last night.
Satellite shows intermittent clouds.

Kevin want to add a 30-second out-of-focus exposure right after standards.
This sounds good. Marisa thinks he has a script ready to fo.
Some g-band SN need to be done, but the Moon is bright.
WF Maybe z- and Y- in tiling 1.

What about the accelerometers?
Can we get the 3D anemometer to Chile in timem for Kevin to put it some place?
