SA: Rudi SO: JC Others: ------------------------------------------------------------------------ Summary ------------------------------------------------------------------------ The clouds kept us closed for most of the night. We eventually managed a few low priority blocks towards the end of the night. Science data taken for: 2023-2-MLT-005 P4 RSS (Monitoring the activity of Be/X-ray binaries in the southern hemisphere) 2025-2-LSP-001 P4 HRS (Defining a new chemically peculiar star catalogue) 2026-1-MLT-006 P4 RSS (x2) (Search for new Galactic symbiotic stars) ------------------------------------------------------------------------

SA: Rudi SO: JC Others: ------------------------------------------------------------------------ Summary ------------------------------------------------------------------------ A relatively quite night. We were interrupted by clouds in the middle and had some technical problems towards the end. Mostly lower priority blocks observed due to the clouds and bright moon.

SA: Rudi SO: JC Others: Devakshan, Lisa, Eben, Wimpie ------------------------------------------------------------------------ Summary ------------------------------------------------------------------------ Managed to get some low priority blocks observed. High humidity forced us to close about half way through the night. Some technical downtime too. Science data taken for: 2023-2-MLT-005 P4 RSS (x5) (Monitoring the activity of Be/X-ray binaries in the southern hemisphere) ------------------------------------------------------------------------
