Notes from the 4PM Meeting¶
- Camera and Telescope - OK.
- Last Night - Dome open for a couple of hours producing data with low transmission and poor seeing that triggered SN field observations. Closed rest of time due to weather.
- DESDM & DQ - 2 SN-field g-band images passed quality cuts. Processing in process. MD5 checksum problem.
- Forecast/Plan for Tonight - ObsTac run. LIGO turned on and we have agreement to follow their triggers. 6:30 pm Chile time is deadline for LIGO to provide us with JSON script. Would be in last two hours of the night. Need to change PropID: 2015B-0187.
