We have been taking production data since Yesterday 9:30 am. The total ABU for the past three shifts is 19.4 hours. 

HMS Q3 LHe level went low around 9:30 pm last night, but recovered by itself within minutes. https://logbooks.jlab.org/entry/4278955

The NPS electronics zone chiller has a low level red alarm starting 3:16 am this morning. It's an ongoing alarm. The water should be at 80%, which is Ok. We will add water during the Monday access.  https://logbooks.jlab.org/entry/4279046, https://logbooks.jlab.org/entry/4279146

Some data files under /mss are not duplicated. Please don't delete local data files manually. It will be resolved by CST. https://logbooks.jlab.org/entry/4279153

The shifts are filled for this weekend. Thank people who have signed up. There is still a SL opening on Monday Day shift. Please considering signing up.

The scheduled Moller measurement is changed from Tuesday to Thursday. The current optimistic earliest estimation of Hall A being ready to receive beam is Tuesday Swing shift, so it's likely that the scheduled Beam Study on Wednesday will be postponed by a week. 

There will be No RC meeting today. If you feel a need of having the RC meeting, please let me know.

Have a nice Saturday.
Hanjie Liu - RC
