Night Plan

If LBCs unavailable

• OSCO at Twilight
• Speckle test (1.5hr) - D. Thompson
  • M 56 19:16:35.57 +30:11:00.50
  • M 15 21:29:58.00 +12:10:01.00
• Neptune Observations (Triton as AO Ref star) - optimal 8-10pm local time
  • /home/lbto/Service_Observing/Eng_D_Oct_25_31_2020/Planet_Scripts
• GRB 200826A - H-band Imaging with Bin 4 AO - (2hr) - if seeing is 1.2" or better
  • /home/lbto/Service_Observing/Eng_D_Oct_25_31_2020/GRB_200826A
  • Observe the PSF star first
• ESM tests as time permits - executed in any conditions
  • Located in: /home/lbto/Service_Observing/Eng_D_Oct_25_31_2020/ESM (OBS-N)
  • M52 (sets 2nd half) AORef=10.7 and 15.2 - highest priority
  • M34 (rises above elevation 19:30hr) AORef = 12.4
• Poor Weather Backup
  • If conditions are too poor to start with Speckle-test after OSCO
    • ESM M52 AORef R=10 (all 3 bands)
    • Neptune - regardless of conditions - want to improve and document technique
    • ICRF3
  • Science Backup Targets
    • /home/lbto/Service_Observing/Eng_D_Oct_25_31_2020/Poor_Weather
    • H-band Library (LUCI) - only if super poor seeing AND thick clouds (only brightest stars left)
    • ICRF3 Followup (LUCI)
      • Order of observations (priority/time):
      • IERS_0017+200 - visible 1st half
      • IERS_2320+689 - visible 1st half
      • IERS_0426+273 - visible 10pm onwards
      • IERS_0141+268 - visible 7:30pm onwards

if LBCs available

• LBC Twilight flats (if skies clear enough)
• LBC Pointing Model (2hrs)
• Reconfig to LUCI-Bino, authorize LUCI-1
• Neptune observations - regardless of seeing conditions
• GRB 200826A - H-band Imaging with Bin 4 AO - (2hr) - if seeing is 1.2" or better
  • /home/lbto/Service_Observing/Eng_D_Oct_25_31_2020/GRB_200826A
  • Observe PSF star first
• ESM as time permits - or poor seeing

Closed Dome

• LUCI-SOUL
• LUCI cals
  • G200 zJ(L1) HK(L2) 1" longslit flats (ICRF3 cals directory) - for backup poor weather programs
  • G200 zJ(L1) and zJ(L2) 1" longslit flats (ICRF3 cals directory) - taken in case either LUCI becomes unavailable at night - low priority
  • Finish off any N30 flats missed
