- Alexandre just noticed that Tagger magnet NMR communication is down again [26]
- DIRC major alarm has been acknowledged [27], Mark may need to investigate this issue more

Wednesday, July 6
Past 24 hours
- Malte and Mark worked on FCAL bases replacement [32]
- One of the RF crates had been disconnected, Beni fixed it [33]
- Bobby and others worked in the tagger hall during the day. At 3:30 pm Bobby noticed that the IOC for the NMR was not responding properly. MCC rebooted the IOC crate. Afterward, it was still locked on zero and there was still a Comm Status error [34]
- Beni found that the solenoid controls hung, and restarted the ramping, which was helpful.
- Had minor issues with DAQ at 7.00 pm: ROCFDC11 error: timeout error on FA125, every 3 seconds. (fADC125 in fdc11 slot 3 was replaced during daytime [35]) Sergei worked out the DAQ issue at 7.50 pm
- Established operating field of the solenoid at 8:30 pm.
- harp scans are ongoing now
