(All times are MST)

Night crew:

Mountain: Steve A.

Tucson: Michelle, Barry, Jenny, Shane, Andrew

Summary

LBTO Service Observing for INAF. Started the night with medium priority Polletta MOS mask B in good seeing (0.8"-0.9") but light cirrus and finished 3/5 sets before starting high priority
De Barros MOS program in good (0.6-0.8") seeing. Successfully completed 4 sets of observations and telluric, finishing the program. Ended the night with another Polletta target, Mask C.

Sunset @18:58. Once the Darks completed Steve took over and is opening. Will perform pointing check near first target



First target Standard HIP54188 for Poletta Mask B. Cirrus.

19:49 Slew to First target. Seeing is 0\x94.8 - 0\x94.9

19:55 Starting acq Polletta Mask B

20:01 Starting telluric (img #40) for Polletta Mask B

20:09 Slewing to science target Polletta Mask B LUCI MOS

20:10 Starting acq Polletta Mask B

20:34 Starting science img #50 Seeing ~0\x94.85, thin cirrus; Polletta Mask B

21:00 Seeing at ~1\x94.1

21:33 Repeating script, but need to do 1\x94 offset to return to starting position. Seeing on guider ~0.8\x94

22:26 Repeating script for third run, 1\x94 offset to return to starting position. Seeing on guider = 0\x94.67

@23:00 AM=1.459, seeing 0.75\x94 on guider. 8 120sec exp remaining in current Poletta script.

23:10 Shell RIP, img #106 bad, #105 possibly bad; did not lose preset. Fixing RIP and continue

23:26 Doing two extra obs to make up for bad images, offsets +3, -2. Airmass at 1.6, seeing 0\x94.85

Summary: Completed 3/5 of Poletta Mask B + Telluric before object was below Airmass limit and time to slew to high priority De Barros. Conditions were stable with 0.8-1.0" seeing and light cirrus



23:32 0\x94.8 on guider. Slewing to De Barros, Telluric.

23:40 Starting acquisition. Pointing was spot on, as it has been all night. It seems the issue from last night was resolved.

23:49 Observing De Barros Telluric. 0\x94.75 on guider.

23:58 Image quality is degrading a little. We plan to take the telescope to high elevation and re-flatten the primary before moving on to our science.

00:04 Slewing to Science Target for De Barros

00:09 Collimation complete, beginning acquisition Science Target for De Barros

00:27 Starting science De Barros

00:45 Seeing at 0\x94.8 on the guider

01:00 starting Second run

01:07 0\x94.5 on guider.

01:34 starting Third run

02:09 starting Fourth run. Seeing stable at ~0\x94.5 (total 7/7 for 3.5 hours total on mask)

Summary: Completed 4/4 of De Barros mask and 7/7 over last too nights. Seeing was good (~0.5 - 0.8) with light cirrus. Telluric



02:44 Slewing to Polletta Mask C. 0\x94.63 on guider.

02:51 Acquiring Polletta Mask C

03:10 Starting science. Polletta Mask C

03:58 Seeing is worsening, up to 1\x94.1; Finishing Set 1 Polletta Telluric Mask C; doing part of a set to make up for any signal loss and to finish out night.

04:22 Slewing to Polletta Telluric Mask C. Seeing back to 0\x94.6.

NOTE: No finding chart provided. Two bright stars centered in the field. The first taken is the fainter F2V star (HIP91783 matching the xml script name). Will take the G2IV (brighter one HIP91782) after.

04:34 F2V science exp started. Polletta Telluric Mask C

04:41 Reacq for G2IV in Polletta Telluric Mask C

04:48 G2IV telluric started at 4:48. Very bright, Nonlinear (K=7.8).
