SA: Lee SO: Fred Others: Nikki, Lisa, Malcolm, Shan, Jake ------------------------------------------------------------------------ Summary ------------------------------------------------------------------------ We spent some time on commissioning tasks early on in the night, including some SMI-300 and LFC observations. We spent most of the night closed to high humidity and some thick cloud, completing two blocks in the brief period in between. Science data taken for: 2024-2-COM-002 P1 RSS (This is a commissioning proposal) 2025-1-MLT-004 P1 RSS (x2) (Near-UV and visible spectroscopy of the primitive asteroids) ------------------------------------------------------------------------

SA: Lee SO: Fred Others: Nikki, Lisa, Malcolm, Shan, Jake ------------------------------------------------------------------------ Summary ------------------------------------------------------------------------ We were closed to bad weather for the first half of the night, but opened just before midnight when the humidity dropped. The seeing was variable, but we managed mostly high priority blocks with a dark moon. Science data taken for: 2026-1-SCI-015 P1 RSS (x3) (Investigation of activity among main-belt objects) 2025-2-MLT-013 P1 RSS (Searching for double hydrogen-deficient stars) 2026-1-SCI-008 P1 RSS (Determining mass of 2 Brown Dwarfs orbiting WD stars using Radial Velocities) 2026-1-SCI-004 P1 HRS (Studying the variable stellar winds of Wolf-Rayet stars) 2026-1-SCI-022 P1 RSS (Identifying targets for follow-up BH dynamical mass measurements) 2026-1-SCI-025 P2 RSS (x2) (We are probing the large scale outflows in bright quasars through absorption spectroscopy.) ------------------------------------------------------------------------
