SA: Lee SO: Veronica Others: Nico (Dimm) ------------------------------------------------------------------------ Summary ------------------------------------------------------------------------ We marked the mid-point of the semester with a productive night and only minor downtime. The bright moon and thin cloud meant we stuck to mostly lower priority blocks, though a handful of P0-2 blocks found their way into the queue. A total of 20 blocks were completed. Science data taken for: 2024-2-LSP-001 P0 RSS (Followup of Transients) 2026-1-SCI-020 P1 RSS (Finding presence of Supermassive black hole binaries in quasars) 2026-1-COM-001 P1 HRS (HRS HS Commissioning ) 2025-2-MLT-013 P2 RSS (x3) (Searching for double hydrogen-deficient stars) 2025-2-MLT-004 P3 HRS (Radial Velocity Monitoring and Atmospheric Parameters Study of Yellow Symbiotic Giants) 2025-2-MLT-012 P3 HRS (x2) (Search for binary stars which may form planetary nebulae.) 2026-1-MLT-006 P3 RSS (Search for new Galactic symbiotic stars) 2026-1-SCI-004 P3 HRS (Studying the variable stellar winds of Wolf-Rayet stars) 2024-1-MLT-010 P3 HRS (x2) (Stellar Characterisation of Ariel mission targets: derivation of N and O abundances) 2026-1-MLT-002 P3 HRS (HRS-MR spectra of Classical Cepheids ) 2025-2-LSP-001 P4 HRS (x5) (Defining a new chemically peculiar star catalogue) 2023-2-MLT-005 P4 RSS (Monitoring the activity of Be/X-ray binaries in the southern hemisphere) ------------------------------------------------------------------------

SA: Lee SO: Veronica Others: Dev, Nico, Thabelo (for mirror) ------------------------------------------------------------------------ Summary ------------------------------------------------------------------------ What a deeply frustrating night! We battled with the mirror for nearly 6 hours before starting observations. The battle then shifted to variable thin/thick cloud affecting almost every exposure. Our one saving grace was good seeing and good IQ after the alignment. We completed 10 blocks, including a P0.
