Unfortunately the seeing starts off at 2.7 arcsec, so Vincenzo has plenty of opportunity to take standards.

01:35 - Slew to standard field SA110 and do IA

Initial seeing is 2.7', more or less like yesterday.
Although the night is probably photometric, we'll take two or
even three standard fields before deciding what to do with the
targets. At current point, it' s meaningless to do any program, but
repeat Ryan's one.
