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

Good weather and modest seeing allowed us to complete several blocks tonight. These were mostly of lower priority due to the bright moon. We lost a small amount of time to technical issues, but otherwise had a good night.

2024-2-MLT-001 P2 HRS (Spectroscopy of compact heirarchial triples)
