SA: Moses SO: Veronica Others: Austun, Alexei ------------------------------------------------------------------------ Summary ------------------------------------------------------------------------ We lost most of the night due to bad weather - bad seeing and high humidity, and only managed to observe a few blocks. Science data taken for: 2026-1-MLT-003 P4 RSS (x2) (RSS longslit observations of Hickson Compact Groups) ------------------------------------------------------------------------
