Observing Plan and Goals for the Night

*Install new, untested obstac 5.14.1 to deal with offsets during SN observations
*Standards, Obstac, more standards

Prioritization for tonight's observations:
  1. Photometric standards sequence as soon as dark enough (Yzirg in 3 fields at different
  2. Obstac (no later than -18 twilight start)
  3. Morning standards (must end by -10 twilight)

Notes from the 4PM Meeting and Additional Comments

*Long discussion about issues with supernovae. Yes, we do observe at airmass 2. There was a mis-communication between obstac and SISPI about how to deal with offsets, since the first SN exposure should be used to adjust the pointing. We will try a new obstac to see if it can handle the problem. Last night the pointing in SN fields was outside acceptable limits.
*Data are going to NCSA first.
*We will not be declaring data bad for the time being.

Proposal ID is 2012B-0001
