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.
