    SL: Min Huang 
    TO: Toby Badman 
    3rd: Mohamed Hafez 
    
    0:00 Shift starts with production runs at 1.441GeV
    1:20 kalyan suggested to ask MCC changing BPMA/B positions to the values
    we had during swing shift. Kalyan and Chao were watching bpm positions
    and 3rd arm rate.
    1:50 Kalyan suggested asking MCC to change IH01.xpos from -3 to -4, then
    all the way to 0. 3rd arm rate came back to 1.7k good value. 
    1:55 Continue production runs at 1.441GeV
    4:10 Finish production at 1.441GeV. Changing HRS p0 to 1.3405GeV.
    The septum currents were found wrong later. 
    4:22 Hall C change IHWP to be OUT.
    Beam trip. Take a bleed-thru test.
    5:40 Turn on slow raster. Cycle LHRS to 2.228 elastic setting and set
    septum current to get ready for packing fraction runs. Take on NH3
    top&bottom.
    6:25 Move LHRS to 1.3405, set septum currents accordingly, turn off slow
    raster, retake dilution runs.
    7:15 Turn on slow raster, move target to NH3 top, polarized to 28.8%,
    start production runs at 1.3405GeV.
    8:00 Shift ends with production on-going.
