Current status
1) Halog entry about summary of  present kinematic outlook : https://logbooks.jlab.org/entry/3954851
2) Beam has beam fairly good.
3) Have about 2260 pions fro present setting.

RUn plan
Day :
1)LD2 Q2=3.85, W=3.07, x=0.31, low epsilon, HMS angle=35.12 deg, HMS momentum = -1.332 GeV/c, SHMS angle= 6.39deg, SHMS momentum=-6.538 GeV/c;
2) Need daily one hour trigger 3/4 runs.
3) BCM calibration at 2:30
Swing:
1) LD2 Q2=3.85, W=3.07, x=0.31, low epsilon, HMS angle=35.12 deg, HMS momentum = -1.332 GeV/c, SHMS angle= 6.39deg, SHMS momentum=-6.538 GeV/c;
Owl:
1) LD2 Q2=3.85, W=3.07, x=0.31, low epsilon, HMS angle=35.12 deg, HMS momentum = -1.332 GeV/c, SHMS angle= 6.39deg, SHMS momentum=-6.538 GeV/c;

FADCmode 10 run 13695 taken on Saturday.
Take the 2.5 hours Al dummy at end of running on Saturday morning.

Notices in Effect for Shift Crew
1) The Raster Coil pair Ax and Ay are off. Raster needs to be at 4x4.
2) With LHe alarms it is good to check the cameras for plumes. If no plume and it is below the LO alarm and above LOLO then monitor with a plot and halog the problem.
3) With LNitrogen alarms are not that critical. Just need to start monitoring the problem with plot and halog.

Current Issues
1) The Raster Coil pair Ax and Ay are off
2) Elevator is not working
3) Noticed bug in Prescale GUI
