Summary:

LBTI AO checkout completed. Pased with flying colours. We were able to perform a rough focus on LMIRcam with the ARGOS source as well. Dave took the data for the LUCI1 wavelength calibration. I verified the mirroring of mask 921459.VIPE1

Problems:

1. LUCI-2 CCR offline - unavailable as of afternoon

Proposed Plan:

• LUCI-1 - CRITICAL PRIORITY
• PFS Alignment Alignment - daytime - into handover if needed - CRITICAL
• Focus check time permitting (or if weather keeps us closed at sunset)
• L! Rotator Center (0.5 hr) - high
  • M92, M34, or M52 - fields available for all night
• L1 Rotator ZP for AGW - (1 hr) - critical
  • Long Slit Method - instructions to be provided by J. Power
    • Suggest doing 3 "masks" to verify the RotZP (based on experience with issues from L2 run)
• AGW Transform for both LUCIs (use the N30 fieldstop, H or FeII filters) - (2 hr) - high/critical
  • Min 15-20 stars needed
    • StoneO
    • StoneL
    • StoneA
• LUCI-1 Imaging check (can run LUCI-2 in parallel to repeat) - high
  • Important to test in and out of field to "stress-test" AGW-1 - does it recover from long throws? and multi-point dithers?
  • Sidereal
    • Dither in-field
      • J1601 (sets around 10pm) - dithering in the field -Kband only
      • NGC 7027 (sets 4am) - cycles through all filters, can stop early
    • Dither out-of-field
      • M52 - (all night) - KJH
      • NGC 40 - (all night) - all filters
  • NS
    • Comet 29/P - (after 10pm) - JHK - need to update for tonight's ephemeris
• Twilight Flats - low
• Photometric Standards - (1-2hrs) - medium - only if clear - any seeing
• AFTER LUCI-1 checkout:
• LBCs
  
  • Collimate WRS/DOFPIA - high (4 x 0.25 hrs) - to check LBC-Blue
  • Superfocus sequence -PA=0,180 high (1 hr) - to check LBC-Blue
  • Rotator Center Checks, start with PA=0, 180 (track mode), then 90,270 - high (1hr) - to check LBC-Blue
  • Test Science OB - guiding - medium (1hr)
    • Sidereal
    • Non-Sidereal
  • Standard Photometric fields - requires clear skies - any seeing
  • Spectrophotometric Standards - requires clear skies - any seeing
  • Twlight Flats
• MODS
  • Spectrophotometric stars if clear (and if not clear only if taking data)
  • Photometric Standards - (1 hr) - only if clear - any seeing
  • Mixed Mode LBC-R/MODS-2
  • Skyflats MODS2-Blue
  • Revisit Transient - (1hr) - Med/High
    • Same spectroscopy scripts (run 2x extra eposures - total of 4x900sec each channel)
    • If too faint for spectroscopy, take u,g,r,i,z imaging - script TBD

Closed Dome Activities

• LUCI-Bino Flexure
• LUCI1 Wavelength Calibration
• LBTI AO Checkout
• SOUL LUCI-1/AO Checkout

1:15 Conditions on the summit: Heavy cloud cover, drizzles earlier. Setting up to run LBTI WFS and AO prerun checkout closed dome

1:32 ARGOS light has been deployed, chamber lights off, in retro mode with M2 and M3 set to last position for LBTI WFS alignment.

  LBTI Checkout: SX AdSec

  Usage on /local/aomeas on lbtisxwfs6 is high at 84% and should be cleared out before run.
• Aligning on M2 M3
  M2: 2.2983, 0.7501, -1.550, 245.0277, -209.0703, 0.
• Loaded KL20 modal basis, usual reconstructions, and LBTI forgetting factor without issue.

• Steve Ertel has LMIRCAM up and running to check image focus.

WFS disconnected from msgD, stopped and restarted the wfs arbitrator

• Updating the Bayside stage positions to 52.8, 24.3 to center the argos source on the center of the LMIRCAM patrol field
  M2: 2.4642, 0.2025, -1.5430,390.32, -162.46 0
• Ran focus sequence with ARGOS source and found optimal focus was around 77.5. Set the
  Bayside Z focus in the LBTI_ACE-AO in /home/sxwunit/aoroot/calib/wfs/current/setups to 78 as a starting point for an onsky focus sequence on a point source.
• Closed with several disturbance files and reconstructors, no issues.

Dave is doing some LUCI1 wavelength work while we work on LBTI AO checkout. He gathered the LUCI2 wavelength data yesterday.

4:07 Steve is deploying the troughs preemptively before Bruce heads to bed.

4:33 Preset AO with AOS commands gui (manually set WFS Spec to LBTIWFS in Flao GUI). Intervention not set and closed and optimized without issue.

Tested a few setups, disturbance files, to be thorough but all looks just as happy as it did prior to shutdown.

For the books:

5:00 Done with the Adsec and LBTI wfs. Warmed the camera and powered off, w_stop. Adsec remains set. Also the rr_mode_enable was activated when I started tonight and I will leave it like that, unless a miracle happens and it looks like we will open.

Will park the ARGOS source once Dave hits a logical break in his scripts and I can turn the lights on (20 min or so).

7:20 Dave finished LUCI1 calibrations

8:50 Checking out some luci masks

• luci1.20200831.0217 921459.VIPE1 in FPU. Confirmed mask is mirrored
• luci1.20200831.0218 moving mask 931032.VIPB4 into the FPU slot 14 and another of the INAF masks. Verified no Xflip for this mask as expected it is just the VIPE1 mask.
• put no mask in use and luci to bed.
