We continued taking unpol H2 data at 0.1 sccm. On nsed, there were typically many hits in the wire chambers with every event and the coda event size was around 2.2 kB. The event size gradually decreased over the duration of each fill.

The coinc physics.settings trigger was used with the physrun configuration file and the Blast field was zero. The wire chambers tripped at times, but were usually quiet.

The HV daemon was rebooted as the Channel Enable (CE) for L14 was set to zero in OPER mode. With CE set to zero in the oper mode, the L14 wire votages were at their usual oper values, except that the guard wire fluctuated from 1900V by +- 50V. After rebooting, L14 CE was set to 1 and the wire behaved normally (including less tripping).
