Date: 2020 Nov 26 UTC Observers: Jack Neustadt, Rick Pogge, Dragon Reed TO: Josh WIlliams SA: Olga Kuhn Special Assistants: Trim, Mrs. Chippy All observers and SAs working remotely from their respective homes. Moon phase: Waxing Gibbous (Illumination: 80%) Summary: Seeing was decent throughout the night (~1"). LUCI projects were completed on time, but large overheads and a long transition from LUCI to LBC kept us from finishing the LBC monitor medium program. MODS is off the telescope Calibrations: another round of twilight sky flats @ K --- done in evening twilight closed-dome imaging calibrations, particularly @ K flats/arcs for UVa_nirjetsLS flats/arcs for UVa_BCD_LUCI darks for UVa_BCD_LUCI and UVa_nirjets, UVa_nirjetsLS, darks at DIT=10s, NDIT=1 for K flats.
