      4. 2020-Oct-29 UT 07:25 for 1:10min : 01 04 07.36 +04 43 57.4 - ´╗┐This would overlap with LBTI, not an option
      5. 2020-Nov-01 UT 04:20 for 1:10min: 01 02 32.31 +04 42 58.3
      6. DONE Take sievemask (opticsieve) with the N30 to map distortions - daytime calibration
    2. Uranus
      1. DONE Ariel R~14 (Bin 3)
      2. Miranda R~16 (Bin 4)
    3. Neptune - too close to the Moon?
  2. UT Oct 27 - AO Engineering Work
    1. Bin 4 observations of stars
    2. Routine observations of "standard" check fields (i.e. M52)
  3. UT Oct 27 - ESM on-sky testing - Arcetri worked on pupil finding issue
    1. M52 (R=10, 15.7 AORef)
      1. DONE ( but unable to close loop on R=15.7) variable poor conditions
    2. M34 (R=12 AORef)
      1. DONE variable poor conditions
  4. Any night - MODS Eng checks for upcoming obs
    1. MMS test on-sky with J. Heidt mask (acquisition only) - 20min Can be done in mediocre weather - just aligning the mask
    2. Defocus check. Pointing to "bright" star, defocus ~ 3" using detector focus. Verify stability for about 10 min. (~20 min task total), seeing ANY, but stable, CC ANY
  5. Any night - Luci / LBC software "blessing" on robs
  6. Any night - LUCI1 pseudo-speckle tests (1.5h) - D. Thompson - execute and prepare scripts
    1. DONE (re-rotator issue, will try again) M15, M56 - beginning of the night (19hrs, 21hrs) - just need to do one
  7. Pointing Model LBC (2hrs) -
    1. Guide being put together by Jenny and Olga
    2. need to convert LBC star list to work with IRAF Ptstars
    3. Readout chip 2
    4. PtStars 20 degree centers
    5. Could be related to trailing issue LBC
    6. Thermal stability important
    7. O. Kuhn will put together set of pointing star scripts for LBC and prep PtStars for UT Oct 29 (Wed)
  8. LBC Skyflats
  9. More flight-time for OSAs on AO
    1. DONE 1x OSCO

Science Programs

  1. UT Oct 31 - PEPSI Program for OSURC
  2. Space Rock Recovery to test LBCs - C. Veillet
  3. AO Followup of GRB 200826A (H-band) - B. Rothberg (2hrs) x2
  4. ESM Spectroscopic confirmation of z~10.5 galaxy in CANDELS - B. Rothberg (2.75 hrs)
  5. Poor Weather Backups
    1. ICRF3 (Rothberg)
    2. H-band Library (Rothberg)
