run029   SA97-249   16/10/2012   06:38:29 06:41:15 21 data FFCLR 2500.0 8281.9 u' BCont HA-N 1 1024 x 1024 1 x 1 CDD 8C0000 -40,-40,-40 3590 W/2012B/14 Southworth eb,jr,jvr 100222   run029   Standard star.

run027   HAT-P-20   16/10/2012   04:21:34 06:28:50 1904 data 2-WIN 2300.0 4012.5 u' BCont HA-N 3 233 x 620 280, 613 330 1 x 1 CDD 8C0000 -40,-40,-40 3590 W/2012B/14 Southworth eb,jr,jvr 100222   run027   Science data. Decreased exposure delay another second and lost another u-band co-add. Counts look ok now. One or two peppers, though this originates from only one of the comparison stars. Still a lot of cloud around.
run026   HAT-P-20   16/10/2012   04:18:15 04:21:27 40 data 2-WIN 3300.0 4928.0 u' BCont HA-N 4 233 x 620 280, 613 330 1 x 1 CDD 8C0000 -40,-40,-40 3590 W/2012B/14 Southworth eb,jr,jvr 100222   run026   Science data. One less u-band co-add to try to avoid further peppering as the target rises.
run025   HAT-P-20   16/10/2012   04:17:46 04:18:03 5 data 2-WIN 3300.0 4232.2 u' BCont HA-N 5 233 x 620 280, 613 330 1 x 1 CDD 8C0000 -40,-40,-40 3590 W/2012B/14 Southworth eb,jr,jvr 100222   run025   Science data. Decreased the exposure delay by 1s.

run023   HAT-P-20   16/10/2012   02:45:30 03:12:45 273 data 2-WIN 4300.0 6008.9 u' BCont HA-N 5 233 x 620 280, 613 330 1 x 1 CDD 8C0000 -40,-40,-40 3590 W/2012B/14 Southworth eb,jr,jvr 100222   run023   Science data. Final tweaks to focus in the first 8 minutes. Keep set-up like this. Very cloudy. At 03:12UT we had to close the mirror. 03:23UT we had to close the dome.
run022   HAT-P-20   16/10/2012   02:31:52 02:45:22 136 data 2-WIN 4300.0 6005.0 u' BCont HA-N 5 233 x 620 280, 613 330 1 x 1 CDD 8C0000 -40,-40,-40 3590 W/2012B/14 Southworth eb,jr,jvr 100222   run022   Science data. Tweaking exposure time and focus. Very difficult to set up in these conditions!
run021   HAT-P-20   16/10/2012   02:23:15 02:31:43 103 data 2-WIN 3300.0 4980.6 u' BCont HA-N 4 233 x 620 280, 613 330 1 x 1 CDD 8C0000 -40,-40,-40 3590 W/2012B/14 Southworth eb,jr,jvr 100222   run021   Science data. Setting exposure time and focus. Counts highly variable due to cloud.

We tweaked the focus some more at the start of the run, but not again after frame 170. Sudden jump in x pixel position of around 5 pixels, moved telescope to accomodate this and a slow drift that has occured throughout. 00:40 UT: clouds moving in. Clouds really bad in the last 100 min of data. Transmission dropping as low as 20 per cent at times.
