Problems:
The scan of filter N540 failed. Temperature of the DECal system went too high shortly after the start of the scan. The liquid in the cooling system seem to be not working (liquid is not flowing). After some attempts to fix it, with no success, and given that the temperature was still high, I decided to call the eng off and go to the sky to observe the DELVE program. I (Kathy) will coordinate with Esteban when to do proper maintenance of the system.
