Ops-PR for tracking. The viewer isn't showing any image on Crosspoint. Already spoke to I&C On-Call, who plans to enter the hall to investigate when it goes down for access on Saturday. We really want this back to help figure if the beam is blowing up before the target, or IHA3H07B just needs troubleshooting.
