run020   Bias   17/10/2012   06:18:53 06:19:22 101 bias 2-WIN .5 282.9 u' g' r' 1 250 x 320 231, 615 41 2 x 2 CDD 8C0000 -40,-40,-40 3590 Calib Calib eb,jr,jvr 100222   run020   Bias frame for windowed set-up we used tonight.
run019   SDSS J065133.33+284423.3   17/10/2012   05:55:23 06:17:06 627 data 2-WIN 1800.5 2080.0 u' g' r' 4 250 x 320 231, 615 41 2 x 2 CDD 8C0000 -40,-40,-40 3590 W/2012B/N17 Groot eb,jr,jvr 100222   run019   Clouds cleared again and we took some pretty nice data for 20mins before guiding went as we approached telescope blind spot.
run018   SDSS J065133.33+284423.3   17/10/2012   05:01:17 05:09:27 237 data 2-WIN 1800.5 2077.2 u' g' r' 4 250 x 320 231, 615 41 2 x 2 CDD 8C0000 -40,-40,-40 3590 W/2012B/N17 Groot eb,jr,jvr 100222   run018   IGNORE. Trying yet again, but no good.
run017   SDSS J065133.33+284423.3   17/10/2012   04:54:06 05:01:12 206 data 2-WIN 1800.5 2079.3 u' g' r' 4 250 x 320 231, 615 41 2 x 2 CDD 8C0000 -40,-40,-40 3590 W/2012B/N17 Groot eb,jr,jvr 100222   run017   IGNORE. Trying again, but it's of no use.
run016   SDSS J065133.33+284423.3   17/10/2012   04:19:08 04:49:12 868 data 2-WIN 1800.5 2081.1 u' g' r' 4 250 x 320 231, 615 41 2 x 2 CDD 8C0000 -40,-40,-40 3590 W/2012B/N17 Groot eb,jr,jvr 100222   run016   Science data finally, and it's looking very good! Runs 012 to 015 almost certainly contains usable data. Eh, spoke too soon. 30 minutes into the run we lost the target and the guide star. Mirror petals closed.
run015   SDSS J065133.33+284423.3   17/10/2012   04:15:57 04:18:57 117 data caution FFNOC .5 1552.8 u' g' r' 4 1024 x 1024 2 x 2 CDD 8C0000 -40,-40,-40 3590 W/2012B/N17 Groot eb,jr,jvr 100222   run015   Ah. TO realised we were not using the same guiding parameters as two nights ago. Moves the telescope to that position.
run014   SDSS J065133.33+284423.3   17/10/2012   04:13:44 04:15:53 63 data 2-WIN 1800.5 2082.0 u' g' r' 4 250 x 320 261, 695 111 2 x 2 CDD 8C0000 -40,-40,-40 3590 W/2012B/N17 Groot eb,jr,jvr 100222   run014   Science data. Still slightly concerned about peppering, so want to move another (fainter) star further away from the edge of the chip to use it as an additional comparison.
run013   SDSS J065133.33+284423.3   17/10/2012   04:10:15 04:13:38 88 data 2-WIN 2050.5 2330.3 u' g' r' 4 250 x 320 261, 695 111 2 x 2 CDD 8C0000 -40,-40,-40 3590 W/2012B/N17 Groot eb,jr,jvr 100222   run013   Science data. But we are worried that we are too close to the peppering limit in the comparison stars, so we reduce the exposure delay.
run012   SDSS J065133.33+284423.3   17/10/2012   04:03:31 04:10:10 258 data caution FFNOC .5 1552.8 u' g' r' 4 1024 x 1024 2 x 2 CDD 8C0000 -40,-40,-40 3590 W/2012B/N17 Groot eb,jr,jvr 100222   run012   Acquisition. Position not what we expected given that we are using a previous night's guiding parameters, so we are tweaking the position to get target away from bad pixels
run011   SDSS J065133.33+284423.3   17/10/2012   04:02:24 04:03:09 21 data caution 2-WIN 2050.5 2243.5 u' g' r' 4 250 x 320 231, 615 41 2 x 2 CDD 8C0000 -40,-40,-40 3590 W/2012B/N17 Groot eb,jr,jvr 100222   run011   IGNORE. In the rush to get on sky we used 2 window mode to acquire instead of full frame
run010   Bias   17/10/2012   00:41:14 00:46:12 101 bias FFCLR .5 2986.5 u' g' i' 1 1024 x 1024 1 x 1 FBB 8C0000 -40,-40,-40 3590 Calib Calib eb,jr,jvr 100222   run010   Just noticed the full frame fast bias this afternoon was actually taken in slow readout mode. Taking full frame fast bias 1x1.
run009   Bias   17/10/2012   00:20:47 00:21:12 101 bias 2-WIN .5 251.4 u' g' r' 1 135 x 135 63, 724 433 1 x 1 CDD 8C0000 -40,-40,-40 3590 Calib Calib eb,jr,jvr 100222   run009   Ran missbias and got a few runs without biases. Only one to do is a 2-windowed set-up for HAT-P-1, which we missed as we set the bias to an earlier 2-window set-up that wasn't useful for science.
run008   Dark   16/10/2012   23:11:09 23:44:32 101 dark FFNOC 14265.0 20023.6 u' g' i' 1 1024 x 1024 1 x 1 CDD 8C0000 -40,-40,-40 814 Calib Calib eb,jr,jvr 100222   run008   Dark frames. Dome and mirror closed. Slide and compmirror in. Too cloudy to open tonight.
run007   Bias   16/10/2012   16:34:17 16:37:08 101 bias 2-WIN .5 1713.0 u' g' i' 1 233 x 620 280, 613 330 1 x 1 CDD 8C0000 -40,-40,-40 -49 Calib Calib eb,jr,jvr 100222   run007   Windowed bias for HAT-P-20. Slide out.
run006   Bias   16/10/2012   16:29:37 16:31:10 101 bias 6-WIN .5 929.0 u' g' i' 1 160 x 160 150, 660 30 160 x 160 10, 860 350 160 x 160 31, 610 730 1 x 1 CDD -40,-40,-40 -49 Calib Calib eb,jr,jvr 100222   run006   Windowed bias for HAT-P-6
run005   Bias   16/10/2012   16:25:16 16:27:56 101 bias FFCLR .5 1601.4 u' g' i' 1 1024 x 1024 2 x 2 CDD 8C0000 -40,-40,-40 -49 Calib Calib eb,jr,jvr 100222   run005   Good slow bias 2x2.
run004   Bias   16/10/2012   16:21:44 16:24:27 101 bias FFCLR .5 1639.0 u' g' i' 1 1024 x 1024 1 x 1 FDD 8C0000 -40,-40,-40 -49 Calib Calib eb,jr,jvr 100222   run004   Good turbo bias 1x1.
run003   Bias   16/10/2012   16:11:40 16:21:21 101 bias FFCLR .5 5807.7 u' g' i' 1 1024 x 1024 1 x 1 CDD 8C0000 -40,-40,-40 -49 Calib Calib eb,jr,jvr 100222   run003   Good fast bias 1x1. Actually, it loooks like this was taken in slow readout mode - see run010!
run002   Bias   16/10/2012   16:00:03 16:09:44 101 bias FFCLR .5 5807.6 u' g' i' 1 1024 x 1024 1 x 1 CDD 8C0000 -40,-40,-40 -49 Calib Calib eb,jr,jvr 100222   run002   Good slow bias 1x1. Slide in. Red noise as low as it's been all run!
