Good morning,

The past 24 hours, ~70 uA beam has been on target 50% of the time and we completed the Q2=3.87 GeV2 kinematic around 2am.  The spectrometers were then rotated and we went to page 62 of the run plan (Q2=5.0, W=2.95, x=0.39, high epsilon).  Early this morning, the SHMS Q2 LN2 level readback dropped to 0% but was fortunately recovered by Heidi when she power cycled the meter (https://logbooks.jlab.org/entry/4024174). 

Tomorrow at 7:15 am beam will be taken away for RF recovery which is estimated to be 4 hours.  During that time, the Hall C will go to restricted access to bring the aerogel into the hall.  We should plan to go back to beam permit by noon if possible.  

We will meet at 11am to discuss what we can accomplish with the remaining 4 days of 5-pass running and the 4-pass run plan.
