Dec 3 (UT)

Observers: Wen-fai Fong

PI programs: Fong

00:00 UT -- Dome opened.

00:37 UT -- Slew to sky flat field. Sky flat test.

00:43 UT -- Start sky flats.

01:08 UT -- Slew to first science target and start collimation and co-pointing.

01:23 UT -- Start first science target, airmass 1.4, 0.9" seeing.

02:09 UT -- Slew to 2nd science target, collimation and pointing.

02:30 UT -- Start 2nd science target, airmass 1.7, 1.2" seeing.

Mirror temperature and ambient temperature are ~1 deg difference so leading to images that are a bit out of focus.

03:07 UT -- Slew to 3rd science target.

03:13 UT -- Start 3rd science target, airmass 1.3, 0.85" seeing.

03:45 UT -- Vacuum sensor timed out. Re-boot housekeeping.

04:00 UT -- Slew to 4th science target.

04:12 UT -- Start 4th science target, airmass 1.1, 0.9" seeing.

04:55 UT -- Slew to 5th science target.

05:06 UT -- Start 5th science target, airmass 1.1, 0.78" seeing.

06:06 UT -- Blue CCD controller failure. Turn off and turn on power control systems.

06:15 UT -- Skip end of last target and slew to 6th science target.

06:28 UT -- Start 6th science target, airmass 1.3, 0.74" seeing.

07:20 UT -- Slew to 7th science target.

07:30 UT -- Start 7th science target, airmass 1.2, 0.81" seeing.

08:21 UT -- Slew to 8th science target.

08:30 UT -- Start 8th science target, airmass 1.5, 0.9" seeing.

09:20 UT -- Slew to 9th science target.

09:35 UT -- Start 9th science target, airmass 1.6, 0.95" seeing.

11:10 UT -- Slew to 10th and final science target.

11:15 UT -- In the middle of focusing, Blue CCD Controller error. Complaints of bad voltages. Turn off all systems and turn back on.

11:34 UT -- Start 10th and final science target. airmass 1.3, 0.83" seeing.

13:00 UT -- Closed dome. Stopped 10 min short of 12 deg twilight because there were focus issues that would have taken longer than the twilight that we had left, and additional imaging in the unfocused regime was leading to diminishing returns.
