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

2025-1-COM-001 P1 HRS (HRS HS Commissioning )
2024-2-COM-002 P1 RSS (This is a commissioning proposal)

SA: Rudi
SO: Austun
Others: Kevin, Willy Benz

SA: Rudi
SO: Austun
Others:

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

The clouds forced us to close for a large part of the night and made observing difficult throughout. We observed mostly brighter and lower priority blocks due to the weather.

Science data taken for:
2024-2-MLT-001 P2 HRS (Spectroscopy of compact heirarchial triples)
2024-1-ORP-001 P3 RSS (Double white dwarf candidates)
2025-1-SCI-002 P3 HRS (Observations of ssrAp stars)
2025-1-SCI-003 P3 HRS (x6) (Defining a new chemically peculiar star catalogue)
