ENR CTIO Blanco 4-m 2024-06-26

Date: 
Wednesday, June 26, 2024
Telescope: 
CTIO Blanco 4-m
Submitter: 
Kathy Vivas
Submitter Email:

Observer Support: 
Hernan Tirado
Night Assistant: 
Alberto Alvarez
Problems: 

At 9:50 UTC, DECam ran into an error (--> interlock) likely associated with a slew to a very low declination (-80deg). We were not able to resume observations.

Comments: 

Enineering: scan of M464 completed successfully. The calibration lamp however could not be controlled from the main LabView application bu only from the Base Power Utility. A spectrophotometric star sequence (star in each chip) was attempted but unfortunately clouds started to appear at mid-sequence with M411. Sequence aborted and observing was handed to the DELVE program.
