* If non photometric * -

do not do standards, and do bootes_cali fields, and change the midnight fields to NGC3368_10step.ob

* seeing requirement * -

Both UMaII needs better than 1.5" seeing; NGC3368_10step needs better than 1.0" seeing.

* Bad seeing fields * - (2.0")

beginning of the night: SN06ce, GRB080205; mid night: NGC3184P, NGC3351P; second half: bootes_cali.
