Beam didn't look good last night once it made it to the Hall C target harps: https://logbooks.jlab.org/entry/3649343

There were few mishaps on the accelerator side: https://logbooks.jlab.org/entry/3649463 (BTW, I did tell the MCC operator early in the night that this magnets need to be set), https://logbooks.jlab.org/entry/3649473 , https://logbooks.jlab.org/entry/3649464

In the morning while Jay was on site few matchings at 3C20 were attempted but without success:  https://logbooks.jlab.org/entry/3649595. After that the matching quads were returned to design set points and the harp scan at 3C20 looked good again:  https://logbooks.jlab.org/entry/3649597 (it seems to me that we are back to where we were at 4:24 am this morning minus the mishaps: look for IHA3C20 in this entry https://logbooks.jlab.org/entry/3649371)
Jay is still working on it.

Once the harps scans will look good at 3H07 A and B we will:

 --> check the beam on the YAG without and with raster 
--> proceed with the ion chamber calibration for Carbon 6%
--> center the beam with the C-hole target
--> do the ion chamber calibrations for the other targets
--> J/psi run plan

P.S. New harp scans just in: https://logbooks.jlab.org/entry/3649614 , https://logbooks.jlab.org/entry/3649615 **and this: https://logbooks.jlab.org/entry/3649618 **
