Since yesterday, we have been taking data smoothly while the beam was available. Here are some notable things that have happened since yesterday, and the short-term run plan:
</br>
</br>

<ul>
<li>After machine setup for Hall A beam, we got the beam to Hallc around 1 pm yesterday and after checking the beam profile, continued positron data taking for kinematics KinC_x25_1. </li>
<li>Here are the last three shift summaries from <a href="https://logbooks.jlab.org/entry/4281332"> yesterday's day </a>, <a href="https://logbooks.jlab.org/entry/4281603"> yesterday's swing </a>, and <a href="https://logbooks.jlab.org/entry/4281835"> and today's owl </a>. ABU for last 24 hours - 13.6 hours.</li>

<li>Completed the positron data taking around 9 pm and started production for that kinematics continued until 9 am this morning when the Moller polarimeter measurement setup started. </li>


<li>We will move (remotely) the HMS spectrometer to 28.34 deg and set the momentum to +1.956 GeV and the SHMS angle to 27.79 deg to prepare for positron runs for kinematics KinC_x36_1 after the Moller measurement. </li>
<li> After completing the positron data taking, we will set the polarity of HMS dipole to -1.956 GeV to start production for the kinematics KinC_x36_1. This will continue until Monday.

<li> <FONT COLOR=" #ff0000"> There are open shifts next week. Please sign up if you can.  <a href="https://misportal.jlab.org/mis/apps/physics/shiftSchedule/index.cfm?experimentRunId=DVCS-NPS-2023"> Shift signup page </a></li>
</ul>


<br>

Updates from 8 am MCC meeting: 
</br>
<ul>
<li> There will be pass change (4th pass) for Hall C on coming Tuesday.</li>
<li>  Beam studies is moved to next Thursday (from Wednesday). Hall C is not required for this beam study and can get beams during that time.</li>
</ul>



<br>
We will have a regular RC meeting at 11:00 am today in the CH conference room.
