	Day	Waiting for beam
	Swing	Harp scans on 4A and 4B, estimate size at target. If size at target is greater than 100um x100 um, then good to go. Otherwise ask MCC to tune. insert warm C-hole tgt, Request position locks (BPM 4A and 4B) from the white board. Take spot run, analyse and see the C-hole on spectra. Move beam to get C-hole properly. With the proper target center, determine raster currents for 2mmx2mm and 4mmx4mm raster size. When C-hole center and raster current are found, call RC for starting Optics data taking.	checked beam spot size from Harp scan - 143um(x)x209um(y). Good enough for our requirement.
Sun Aug 9	Owl
	Day	Optics commissioning - https://docs.google.com/spreadsheets/d/1SngpqgLLULtcuKD0t9k-A2Cpmxy1jb5bIYnnP8f8zPM/edit#gid=1910123414
	Swing	Continue optics data taking. We are planning to skip +1 dp scan completely. After completing -1%dp scan, we will go to the nominal magnet settings and take watercell data for very high statistics (~10M) for (-0.3,-1.5) BPM A and E positions. After that we will request for an access to take out sieve. Then we will take sieve out C target (with and without raster -1M events) and watercell data 10M events for the above BPM positions. Then we will do detector alignment with VDC and GEMs. Finally Qsq measurements. If we are left with time after completing all above steps, then we may go to +1%dp scan or bulleye scan based on how much time available before MCC pushes for higher current.
Mon Aug 10	Owl	Continue plan from yesterday's swing
	Day	During escorted access, take out sieve slits, move upstream and AT detectors to integrating mode. We are going to start high current beam commissioning after the access.	With out Sieve slits data, alignment and Qsq will be done in Future.
	Swing	Going straight tonight (not through chicane) . Continue High current commissioning -Ion chamber calibration upto 20 uA (compare with Feb calibration data). Commissioning FFB, Start Ca target burn off (Call Silviu before starting the burn off procedure). BMod commissioning (call Ye Tian). Production	Ion chamber calibration is done upto 20 uA. We will use the present calibration to estimate ion chamber setpoints for 50 uA and start burn off at 50 uA (look at here https://logbooks.jlab.org/entry/3824379#comment-29514). We will ask MCC to include ion chamber data upto 50 uA while burn off at 50 uA is ongoing and estimate setpoints at 100 uA.
