Notes from the 4PM Meeting¶

•  Camera and Telescope - Everything looks OK after checked in the morning. Observations should be OK for tonight.
•  Last Night - No observations due to earthquake. CO2 canisters overturned.
• DESDM & DQ - Catching up.
• Forecast/Plan for Tonight - Clear skies. Start with izY with moon. Switch to gri. 1:30 SN X3i 3z, S1, C3r fields. SN fields should finish 3:43. First LIGO sequences at 3:53 am.
  Last time slots with LMC for short exposures. LMC priority over last exposure. Priority is X3i, X3z, gravity, then other SN fields. Do standard stars as usual.
