Type: Standard Operation 
Subject: Lid down operation (second) - 2024  

A second lid down operation took place on April 30, 2024.

The system was energized a few minutes ahead of time.

Starting master synchro value: 47427 (after it was jogged up slightly prior to starting).

Upon startup at 12:51 pm, the system worked fine and lowered the lid. The lowering was stopped at approximately 5" gap as per standard procedure for Operations to perform checks. Furthermore, the lowering was stopped multiple times after that at approximately 0.5" increments for resonator latch checks.

No abnormal observations made. No jogs required. Once again, this was a very smooth lowering process. The lid was fully lowered at 2:00 pm.

Ending master synchro value: 66
