run016   Flat   27/04/2022   10:28:38 10:45:14 174 flat FFNOC .5 5758.9 u' g' i' 1 1024 x 1024 1 x 1 CDD 8C0000 -40,-40,-40 1514 Calib Calib mjg 100222   run016   Sky flats, telescope spiralling. Good g and i flats, counts are low in u (15000). But TO says we need to close.
run015   Flat   27/04/2022   10:11:13 10:28:30 181 flat FFNOC .5 5758.9 u' g' i' 1 1024 x 1024 1 x 1 CDD 8C0000 -40,-40,-40 1514 Calib Calib mjg 100222   run015   Low counts.
run014   Gaia EDR3 5892465542676716544   27/04/2022   08:12:47 10:06:38 1125 data 2-WIN 4100.5 6077.3 u' g' i' 4 512 x 350 1, 513 1 1 x 1 CDD 8C0000 -40,-40,-40 1514 GTO Littlefair mjg 100222   run014   Science data. We are pointing limited, so staying on this target. Seeing 2-3 arcsec
run013   Gaia EDR3 5892465542676716544   27/04/2022   06:32:20 08:06:13 928 data 2-WIN 4100.5 6076.5 u' g' i' 4 512 x 350 1, 513 1 1 x 1 CDD 8C0000 -40,-40,-40 1514 GTO Littlefair eb 100222   run013   Science data. Back on target again.
run012   Gaia EDR3 5892465542676716544   27/04/2022   04:48:20 05:57:49 687 data 2-WIN 4100.5 6076.7 u' g' i' 4 512 x 350 1, 513 1 1 x 1 CDD 8C0000 -40,-40,-40 1514 GTO Littlefair eb 100222   run012   Science data! We are on sky again! Seeing 2 arcsec. The FWHM does not improve with focus adjustments, so we decided to leave it as is for now. Position drift from 50 minutes onwards, by about 40 pixels in Y, 10 in X. Can still be reduced by changing search_half_width and fit_max_shift. The rotator is stuck, so we had to stop.
run011   Gaia EDR3 5892465542676716544   27/04/2022   04:12:24 04:15:53 36 data 2-WIN 4100.5 5963.8 u' g' i' 3 512 x 350 1, 513 1 1 x 1 CDD 8C0000 -40,-40,-40 1514 GTO Littlefair eb 100222   run011   Junk - target drifted out of the field, so TO is redoing the preset. TO confirms problem with the telescope tracking. Argh, it's the rotator again!
run010   Gaia EDR3 5892465542676716544   27/04/2022   04:06:11 04:12:15 61 data 2-WIN 4100.5 6062.8 u' g' i' 3 512 x 350 1, 513 1 1 x 1 CDD 8C0000 -40,-40,-40 1514 GTO Littlefair eb 100222   run010   Junk - field is drifting, TO is resetting the guide star.
run009   Gaia EDR3 5892465542676716544   27/04/2022   03:52:33 04:06:01 134 data 2-WIN 4100.5 6075.4 u' g' i' 3 512 x 350 1, 513 1 1 x 1 CDD 8C0000 -40,-40,-40 1514 GTO Littlefair eb 100222   run009   Science data. Big adjustments to focus. Field starts drifting after 10 min.
run008   Gaia EDR3 5892465542676716544   27/04/2022   03:50:10 03:52:23 23 data caution 2-WIN 4100.5 6062.4 u' g' i' 3 512 x 350 1, 513 1 1 x 1 CDD 8C0000 -40,-40,-40 1514 GTO Littlefair eb 100222   run008   Acquisition

run006   Bias   26/04/2022   22:34:27 22:35:47 51 bias FFCLR .5 1601.4 u' g' i' 1 1024 x 1024 2 x 2 CDD 8C0000 -40,-40,-40 1514 Calib Calib eb 100222   run006   Good slow 2x2 bias. RON2.4-2.7
run005   Bias   26/04/2022   22:29:17 22:34:07 51 bias FFCLR .5 5807.7 u' g' i' 1 1024 x 1024 1 x 1 CDD 8C0000 -40,-40,-40 1514 Calib Calib eb 100222   run005   Good slow 1x1 bias. RON2.3-2.5 as in run002
run004   Bias   26/04/2022   22:24:44 22:27:14 51 bias FFCLR .5 2986.5 u' g' i' 1 1024 x 1024 1 x 1 FBB 8C0000 -40,-40,-40 1514 Calib Calib eb 100222   run004   Good fast 1x1 bias. RON2.8-3.2. Humidity 86% at sunset, so we can't open.
run003   Bias   26/04/2022   22:05:21 22:05:53 21 bias FFCLR .5 1601.5 u' g' i' 1 1024 x 1024 2 x 2 CDD 8C0000 -40,-40,-40 -50 Calib Calib eb 100222   run003   Test. 2x2 slow bias as above.
run002   Bias   26/04/2022   22:01:31 22:03:27 21 bias FFCLR .5 5807.7 u' g' i' 1 1024 x 1024 1 x 1 CDD 8C0000 -40,-40,-40 -50 Calib Calib eb 100222   run002   Test. A few 1x1 slow bias frames to test noise. I can't get hold of the TO to ask if the dome is dark, but RON looks good, 2.3-2.5. Slide in.
