LBTO Service Observing for INAF. Started the night with high priority Guaita in good seeing (0.8"-0.9") which very quickly degraded into very poor seeing 2.0-3.0" and recovered to variable 1.5-2.0" seeing.
Attempted Set 1 of low priority Smart program but ran into many problems with poor scripting and preparation. Worked through this got set and comparison stars complete.
Moved on to De Barros MOS program in better (0.9") seeing. Successfully completed 3 sets of observations and Tellurics
Finished with half of H2 imaging data for Target 2 of Beltran and accompanying telluric.
18:25 David is opening the enclosure.
18:30 Configuring for LUCI2 NB NIR skyflats. Telescope fixed at zenith.
18:35 Guider is on axis.
18:40 Counts in Br_gam are still a little high, ~30k.
18:48 Waiting for levels to drop to a reasonable level. Still too high.
18:54 Almost there, looks like we\x92ll have the first good one at sunset.
18:57 Sunset. First good (~10k) Br-gamma flats.

19:30 Slewing to standard star for Gauita Standard P550-C
19:34 Shell RIP
19:46 Pointing issues. Not on target yet.
19:47 12 deg twilight.
19:53 Initial DIMM seeing estimate: 0.8\x94. Collimating now.
19:56 0.7\x94 on guider. Slewing to Guaita Standard P550-C
19:58 Collimating. 0.8\x94 on guider, AM 1.18.
20:00 ~ 0.8\x94 on Ks image. Massive seeing bubble. Guider now 3\x94, 2.8\x94 on DIMM. Seeing bubble\x85 1.6\x94 on science image.
20:05 Waiting out the seeing bubble.
20:09 Seeing is still grim. We are considering our options but the only possibility is the backup sent to us late this morning (Smart). Searching for appropriate target
20:15 DIMM 2.4\x94, guider 1.8\x94
20:25 Backup program has significant issues with the scripts.
20:35 LUCI MOS issue. Called DThompson; grabber went beyond the rotation tolerance. Only needed an init, but none of us had seen this error before.
21:00 LUCI issue resolved, however we now have another pointing problem.
21:05 Acquiring Set 1 Telluric 3 for Smart; Seeing remains at >1.5. Skies are very clear.
21:16 Acquisition Set 1 Telluric 3 for Smart looks good; starting spectra
21:18 Another scripting issue detected. Script says Hi-res grating and z+J spec filter, checking with Felice
21:33 Script observing Set 1 Telluric 3
21:38 Slewing to Set 1 Science Target for Smart
21:45 Acq images 129-131. Acq image scripts use z+J; fixing.
21:54 Image 132; Acquisition confirmed
21:55 Set 1 Science Target science started
22:02 Slewing to Smart Set 1 Control 1
22:12 Guide star is too faint and seeing too poor, skipping to Smart Set 1 Control 3. Pointing problem; putting mask into FPU while problem is resolved
22:28 Instrument state in scheduler didn\x92t match instrument because of mask in FPU. Scheduler balked; restarted. IT 5814
22:31 Back in business. Slewing to Smart Set 1 Control 3
22:32 Spoke too soon, scheduler weirdness is transpiring (still IT 5814)
22:38 Ok, now we\x92re back in business
22:40 Script issues
22:54 Fixed script, reslewing; Observing Smart Set 1 Telluric 3
23:22 Slewing to next target, Smart Set 1 Telluric 3
23:50 Scheduler problems again.
23:55 Slewing back to previous control target with updated guide star: Smart Set 1 Control 1
00:20 Slewing to next target, Smart Set 9 Telluric 3
Seeing has been improving considerably over the last 30 minutes. We are switching to higher priority programs after this is complete. In total, we completed 1 program target from Set 1 and its telluric and 2 required control stars and their tellurics for Smart.
00:33 Slewing to next target, De Barros Telluric. The seeing has been stable under 1.3 for the last ~20 mins and continues to improve.
01:00 Slewing and acquiring MOS DeBarros Science
01:27 Acquisition done; starting science. First Sequence De Barros Science
02:04 Second Sequence De Barrow Science. Seeing is down to 0\x94.65 on the guider
02:34 Starting the Third Sequence De Barrow Science. Seeing is 0\x94.65.
In good seeing and excellent transparency, we finished 3 Sequences of De Barros high priority MOS mask and its accompanying telluric.
03:08 Switching to imaging Beltran Target 2, H2 imaging. Seeing is 0.8\x94
03:12 Pointing check
03:23 Images are elongated. At some dithers (larger off-source offsets) the guider is vignetted and may be contributing. Seeing is still good (0.8\x94)
03:52 Imaging Beltran Target 2 H2 Imaging continuing. Seeing = 0.7\x94 Transparency = clear
04:10 Seeing has worsened, over 1.3\x94 These last few images 270; 269 may be suspect.
04:15 Seeing definitely worse. Slewing to Standard 1 for Beltran H2 Imaging
04:18 Pointing check again. Resending Standard 1 for Beltran H2 Imaging
04:25 Guide star is too faint, switching to alternative standard target Standard 2 for Beltran H2 Imaging
04:40 Guide star resolved in first standard. Finishing with Standard 1 for Beltran H2 Imaging
Complete Beltran Target 2 H2 Filters in clear skies and good to variable seeing. Seeing started out quite good (0.7-0.8) but softened over course of last 15-20 minutes of science target, so PIs may want to check images.
04:50 12 deg twilight.
05:41 Sunrise
