Also Present: 
Rodrigo Hernandez, Rodrigo Hinojosa
Problems: 

Two small problems at the start of the night:

- At 8:43. An interlock related with the Hexapod. Error cleared with a Configure

- At 8:50. A TCS error. It was necessary to clean the tachometers. All ok after that.

Comments: 

First night on the sky after the FCM maintenance engineering. All worked fine. Star flats were taken in g, r, N395 and N540 (then the field set and the next available field was too close to the Moon). The starflats for the other filters will be taken on Thursday night. Then we took observations for programs 2021A-0124 and 2024A-106058, using the broadband filters griz. No problem at all. This means I did not get to test N708 tonight (nor N1008 but that one was not to be used tonight).
