OWL Shift Cancelled Due to HAM6 Vacuum Gauge Failure Which Is Also Used for Fast Shutter Interlock
Since the HAM6 gauge which failed at 10pm local time is used as part of the interlock system for the Fast Shutter, Jenne made the call to have the H1 down for the night (Owl Shift Canceled)
- H1 in IDLE with the IMC Locked.
Tomorrow we will need to figure out the plan forward for H1 operations. Whatever the fix will require a Work Permit and will need to figure out availability for who can do this work.
