SO: Fred
Others: Wimpie/Ant (for PXI error), Moses, Veronica (for focus)

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

We encountered several PXI errors tonight. Due to the combination of bright moon and poor seeing conditions, we mostly observed medium-to-low priority blocks.

Science data taken for:
2023-2-COM-001 P1 HRS (x2) (HS pipeline observations @dlhwp)
2020-2-MLT-007 P2 HRS (HRS observations of a high mass binary system.)
2023-2-LSP-001 P3 RSS (Spectra of ultrashort period main sequence binary stars)
2023-2-MLT-005 P3 HRS (Monitoring the activity of Be/X-ray binaries in the southern hemisphere)
2021-2-LSP-001 P4 HRS (Followup of Transients)
2023-2-SCI-006 P4 HRS (x3) (Defining a new chemically peculiar star catalogue)
2023-1-MLT-005 P4 HRS (Study of the proporties of chemically peculiar Am stars)
