* Nightly Defocus: None

* Sciene Observations:

  • Start running obstac as usual
  • try cosmos field observations if conditions permit: run u-band scripts (from about midnight local time)
  • run the last 3 exposures from the 1st g-band script, that had high sky brightness

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