Logentry Text:
We took an access yesterday morning to rotate SHMS to 6.17 deg in preparation for running at Q=5 and troubleshoot the SHMS Q1 left lead flow controller: https://logbooks.jlab.org/entry/3974487, https://logbooks.jlab.org/entry/3974486

The access ended around 1 pm and then we had to wait for the SHMS Q1 LHe level to be restored after the SHMS Q1 lead flow valve replacement. We started our first production run at Q=5 around 2 pm. We ran smoothly with the exception of 2 downs due to SHMS Q1: https://logbooks.jlab.org/entry/3974559 and https://logbooks.jlab.org/entry/3974701. Beam centering on target has been slightly adjusted: https://logbooks.jlab.org/entry/3974834

We now just recovered from the SHMS Q1 insulating vacuum down and we are about to take production beam again.

We will have an RC meeting today at 10 am: https://jlab-org.zoomgov.com/j/1607100885?pwd=ZFBsRTFsYm5Zb0laZ0tyZXNjcEE0QT09
