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.

SA: Lee SO: Fred Others: Nikki, E10, Lisa, Malcolm ------------------------------------------------------------------------ Summary ------------------------------------------------------------------------ We lost a bit of time at the start of the night due to guider mapping issues, but the rest of the night was fairly smooth.

SA: Alexei SO: Veronica Others: ------------------------------------------------------------------------ Summary ------------------------------------------------------------------------ => In the early hours of the night, the telescope was shut down due to high humidity. The humidity then dropped and we began our observations. Most of the observation blocks we observed were high priority and required dark sky conditions for the observations.
