Observing Plan and Goals for the Night

* Evening Standards: Yzirg.


* Nightly Defocus: None

* Sciene Observations:

  • Start running obstac as usual, and try cosmos field observations if conditions permit
    • if seeing better than 1.1'' run g-band script (from 00:20 local time)
    • if seeing better than 1.05'' rerun the 2nd i-band script (end of half night)

* Midpoint standard (using calspec) use only 1 (highest airmass): grizY
