Notes from the 4PM Meeting¶

•  Camera and Telescope - No problems.
•  Last Night - Dome was not opened. Did DECal.
• DESDM & DQ - Will look at this after phone con.
  *  Forecast/Plan for Tonight - ObsTac run. SN X field later in the night.
• New ObsTac installed: Tweak 1) 20 degree moon hard cut fixed. Tweak 2) redder bands during dark time reduced.
• Nightly calibration. Eric will upload new SISPI. We will ask Hernan to relaunch SISPI.
