Observers: Steven Villanueva, Roberta Humphreys, Rick Pogge Support Astronomer: Michelle Edwards, D. Thompson remote at start Telescope Operator: Geno Bechetti Summary Full night, LBC + MODS. Starting with LBC. Some cirrus coming over us, but mostly thin filaments of stuff. Warm during the day and temps in pretty good control, humidity low. Will have to keep a watch on the wind and cirrus tonight and tomorrow night. When we went to switch to MODS1 at midnight, we ran into a fault with the telescope, not removing the blue LBC camera. After about 2h of trouble shooting, decided problem was pretty severe and switched back to LBC for the rest of the night. Cirrus clouds got progressively worse through the rest of the night, but seeing was mostly subarcsecond. Lost ~2.5h to the failure of the swing-arm system and diagnosis that it was safe to get into LBC mode for the night. Probably could have made that judgement sooner but conditions were poor at the time so there was little urgency (and we were not sure what was and was not stuck). 11-hour nights. Oof. PEPSI time share will start Sunday. Details: All times are UTC unless otherwise indicated LBC 01:40 - ND_SN09ig as twilight is past us, thin wispy cirrus about, crescent moon up in the west. 01:47 - Copointed, seeing in R is ~0.7-0.8 01:54 - Starting OB 02:14 - Stopped, red PSFs are garbage, same trefoil like panel on right/red, but blue is nice and round. 02:16 - Re-running dofpia to correct red, after clearing active optics on both sides. 02:22 - red is better now, back to science field. First image is much better, 0.7 arcsec 02:50 - FWHM starting to degrade on last image, clearly focus change 02:55 - NGC 628 (OSU_Monitor) - focus and co-pointing - 0.8 arcsec seeing 03:05 - Starting OB on target. Seeing 0.6-0.7, last was 0.8, blue was 0.9-1.0 except at U 03:43 - M82 (OSU_Monitor) - focus and co-pointing - seeing bad. 1.7as, still too low, deferring until later (Chris K - if you want good seeing, you need HA range limits!) 03:58 - UVa_WISEimages - 0204+09. focus, but no co-pointing OB given. Had to do a manual co-point (please, people, RTFM) 04:12 - Science OB started after manual co-point. Seeing 0.8as 04:40 - UVa_WISEimage - 0612-06 - focus and manual co-point 04:48 - Science OB started. Seeing 0.9 arcsec on co-point image. First images 0.8as 05:03 - On image 6, seeing now 1", but still mostly round. Last images 0.9as 05:14 - OSU_Monitor NGC2403 - only thing high enough, buys time for M82 05:27 - Science OB start. Seeing 1.1 arcsec on red and round. 05:36 - OSU_Monitor M82 (again) - seeing degrading, now about 1.6, trying M81. We had to clear active optics and run dofpia a 2nd time as the first go there was a huge red/blue discrepancy (red worse than blue) 05:57 - OSU_Monitor M81 - try to get something as seeing degrades 06:06 - Seeing 1.8as, some clouds threatening. Only 4h into an 11h night, so we'll see if this is a bump or the rest of our night... 06:11 - First images is 1.2 arcsec, so better. Last red image 1.5, so bouncing around 06:32 - M82 Science OB - seeing and clouds both conspiring against us. Seeing 1.2 arcsec red 06:38 - Wind coming up, 15m/s in gusts, closing rear vent doors. Last image was 1.8 arcsec 06:45 - Conditions degrading from a good start. Switching to MODS, start with calibration stars, and interleaving with LBC biases. MODS1 07:00 - MODS1 startup completed. Waiting for swing arm... 07:04 - Left side swing arm halted, had to restart MCSPU, waiting... 09:00 - Not going to happen, can't move LBC-Blue out of the way. After lots of phone calls, this is a daytime fix. But we can put LBC-Blue back in play, so... Back to LBC... 09:20 - On IC2574 field to collimate, gauge seeing, and see what we can do. Note: more cirrus now than before, so definitely not photometric 09:25 - Off to IC2574 science field - 1.0 arcsec on image 1. So far so good. Cirrusy, though. 09:37 - To M82 (best placement yet), fingers crossed... blue good but red worse. re-ran dofpia, better 10:00 - Running science OB on M82, seeing 0.9 in red. Wind up a little and cirrus 10:12 - NGC 3077 - focus and co-point, 0.8 arcsec seeing in red 10:23 - First images good, 0.9 arcsec. 10:34 - NGC 2903 - focus and co-point, 10:48 - Science OB started, seeing 0.8 arcsec in red at start, but variable transparency has been degrading throughout the past hour. Seeing fairly steady at 0.8-0.9arcsec 11:30 - focus check, repeating because of transparency degradation. 11:39 - Science OB starting round 2: 0.8 arcsec 12:20 - NGC 4236 - focus and co-point, seeing and transparency deteriorated during 12:30 - Science OB started (nothing else to do). - crap, little signal. 12:40 - called it a night. Geno closing up and we'll take biases to finish. ------------------- Will take BinoBiases at the end after the doors are closed and the telescope returned to zenith. Will update later.
