Experiment Status:
On Saturday we took a Bull's eye scan and production data on Tungsten foils. Sunday in the early morning the LCW leak in Hall C brought down all our magnets and power supplies (https://logbooks.jlab.org/entry/3654919). We went to controlled access to check the magnets and also adjusted the trigger timing (https://logbooks.jlab.org/entry/3655062).  Until the end of Sunday we were able to bring back all HRS magnets but more work has to be done for the septum. 
The LCW system is recovering. The water flow is back and the conductivity is ~2.5 uS/cm^2 this morning ( standard is ~0.5 uS/cm2).
On Sunday monring we noticed that the VESDA box had some flashing yellow lights. (https://logbooks.jlab.org/entry/3654976). According to Tim Minga "Vesda network went down. All have been reset as of 13:35 hours."

Hall Status:
Hall is in controlled access for the septum work. All HRS magnets are set to 0. Shift workers are asked to report by 1pm.
