Night Log 2026-10-31

SA: Lee SO: Veronica Others: ------------------------------------------------------------------------ Summary ------------------------------------------------------------------------ Super night to end the semester! No technical issues and very little weather downtime, despite a very cloudy start to the night. We ticked off a final handful of high priority blocks once the cloud cleared out. The seeing was good and stable throughout, even sub-arcsecond for the last block of the 2026-1 semester. Tomorrow we welcome in 2026-2 :) Science data taken for: 2026-1-MLT-004 P0 RSS (x2) (Observations of supernovae, near and far.) 2026-1-SCI-005 P2 HRS (x3) (na) 2024-2-LSP-001 P2 RSS (Followup of Transients) 2024-2-LSP-001 P2 HRS (x2) (Followup of Transients) 2026-1-SCI-009 P3 RSS (Extreme variability in the BLR of the AGN HE2129-3356) 2023-2-MLT-005 P3 HRS (Monitoring the activity of Be/X-ray binaries in the southern hemisphere) 2026-1-MLT-003 P4 RSS (RSS longslit observations of Hickson Compact Groups) 2023-2-MLT-005 P4 RSS (Monitoring the activity of Be/X-ray binaries in the southern hemisphere) 2026-1-SCI-002 P4 HRS (detached eclipsing binaries for PLATO mission) ------------------------------------------------------------------------

SA: Lee SO: Veronica Others: Lisa, Malcolm, E10, Eben ------------------------------------------------------------------------ Summary ------------------------------------------------------------------------ Another night of great weather allowed us to complete a handful of high priority blocks, despite a few technical issues early on. The seeing was excellent until midnight and became poorer and variable in the final few hours of the night. Science data taken for: 2026-1-MLT-004 P0 RSS (Observations of supernovae, near and far.) 2026-1-MLT-005 P1 RSS (Extreme variability in the BLR of the Seyfert AGN J0259-2422) 2024-2-LSP-001 P2 RSS (x2) (Followup of Transients) 2024-2-LSP-002 P2 RSS (x2) (Pan-African AGN survey using SALT/IFS: tracing the properties of AGN and their host galaxies) 2023-2-MLT-005 P4 RSS (Monitoring the activity of Be/X-ray binaries in the southern hemisphere) ------------------------------------------------------------------------

SA: Lee SO: Veronica Others: Michael, E10 ------------------------------------------------------------------------ Summary ------------------------------------------------------------------------ A smooth night with a bright moon, clear skies and good seeing. We completed a dozen blocks of mixed priority.

SA: Rudi SO: JC Others: Lee, Ian, Lisa ------------------------------------------------------------------------ Summary ------------------------------------------------------------------------ Clouds prevented us from observing at the start of the night. Alternating thick and thin clouds made things a little difficult in the middle, but the clouds finally moved away and allowed us to observe some higher priority targets towards the end of the night. Science data taken for: 2026-1-MLT-004 P0 RSS (Observations of supernovae, near and far.) 2026-1-SCI-001 P2 HRS (Tracing evolution of recent stellar merger remnants) 2024-2-LSP-001 P2 RSS (Followup of Transients) 2024-2-MLT-001 P3 HRS (Spectroscopy of compact heirarchial triples) 2025-2-MLT-004 P3 HRS (Radial Velocity Monitoring and Atmospheric Parameters Study of Yellow Symbiotic Giants) 2023-2-MLT-005 P4 RSS (x2) (Monitoring the activity of Be/X-ray binaries in the southern hemisphere) 2024-1-MLT-010 P4 HRS (Stellar Characterisation of Ariel mission targets: derivation of N and O abundances) ------------------------------------------------------------------------

Night Log 2026-10-26

SA: Rudi SO: JC Others: Lisa, Malcolm, Eben, Wimpie, Ian ------------------------------------------------------------------------ Summary ------------------------------------------------------------------------ Some technical problems at the start of the night and then high humidity. A sudden drop in humidity towards the end of the night allowed us to observe a few high priority targets. Science data taken for: 2026-1-MLT-002 P1 HRS (HRS-MR spectra of Classical Cepheids ) 2025-2-MLT-012 P2 HRS (Search for binary stars which may form planetary nebulae.) 2024-2-LSP-001 P2 RSS (Followup of Transients) 2025-2-LSP-001 P4 HRS (Defining a new chemically peculiar star catalogue) ------------------------------------------------------------------------

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) ------------------------------------------------------------------------
