Observers: Georgios Dimitriadis, Miika Pursiainen Support Team: Southampton TAT on duty: Regis Cartier, Joe Lyman All following times in UT The night is NOT photometric Weather conditions: Start - Few thin clouds in the north, no wind, seeing ~0.6-0.7” Middle - Clear skies, excellent seeing, reaching 0.4-0.5” at its best End - Clear skies, seeing ~0.8” Calibrations: PESSTO_SOFI_FlatJHK PESSTO_SOFI_specflat PESSTO_SOFI_SpecArc PESSTO_calib PESSTO_bias PESSTO_SkyFF_eve_BR PESSTO_SkyFF_mor_UVi NOTE: Regarding yesterday’s issue with the slight elongation on the images, the TOs run tests in the morning and the telescope is in excellent condition. They came to the conclusion that the issue was probably temperature related. For this night, we will continue checking the acquisition images and if we see distortions, we will re-focus.
