Summary:

• 16:00 - Shift starts with the target anneal ongoing
• 16:40 - The left HRS and septum are set to 2.228 GeV for packing fraction
• 16:47 - The right HRS and septum are set to 1.859 GeV
• 17:10 - Hall is now in Beam permit, target anneal done
• 18:55 - Done adjusting beam positions to center on the target beam positions, centering image
• 19:07 - Done checking slow raster, set to 1.9 cm slow raster spot plots
• 19:13 - Starting packing fraction runs spot on NH3
• 19:31 - Bleedthrough measured, 0.5% link
• 19:33 - Done with packing fraction runs, starting to polarize the target
• 19:35 - Changed the LHRS to 1.859 GeV
• 19:54 - Target polarized, starting production
• 20:14 - Ramping to 1.729 GeV
• 20:25 - Found lumi channel 7 tripped, leaving off (trips when trying to turn on), there is no audible alarm on this
• 20:49 - right arm is settled
• 23:50 - IHWP changed to IN
