Doing OK.
NuMI Experiments
Running well. Thanks for notification about the downtime so they could restart their run.
Muon Rings
Lithium lens failure occured on Friday. Water conductivity and pH are characteristic of a septum failure. Repair planning meeting is in progress and it is hoped that beam could be run as early as late Tuesday. Stay tuned for updates in the log.
Other issues include a PRAC problem with V003 but a fix has been implemented and will be tested.
May access delivery ring to appply vacseal to a small leak.
If there is a time with no beam going to MI, they would like to access Transport enclosure for at least an hour.

Requesting a ~4 hour notice before beam returns to do a trolley run.
