Summary
------------------------------------------------------------------------

=> A clear night with a highly variable image quality that was good enough at the beginning of the night, but deteriorated greatly towards the end. Many high priority blocks were observed mainly, but some low priority blocks were observed for the reason of bad seeing.

Science data taken for:
2024-2-LSP-001 P0 RSS (x2) (Followup of Transients)
2024-2-MLT-006 P1 HRS (HRS observations of a high mass binary system.)
2023-2-MLT-003 P1 RSS (Investigating the polarised nature of TeV-emitting blazars)
2024-2-SCI-010 P1 HRS (SALT/HRS observations of a gamma-ray bright HMXB in the LMC. )
2024-2-SCI-025 P1 HRS (Looking for proto hot Jupiters)
2024-1-MLT-001 P2 RSS (x2) (Study of the outer parts of lenticular galaxies.)
2024-2-MLT-001 P3 HRS (Spectroscopy of compact heirarchial triples)
2024-2-SCI-003 P4 HRS (x2) (Defining a new chemically peculiar star catalogue)
