Here are some notable things that have happened since yesterday, and the short-term run plan:
</br>
</br>

<ul>
<li> The SHMS Dipole flow <a href="https://logbooks.jlab.org/entry/4443061"> controller replacement work</a> went smoothly. Many thanks to the Hall C Engineers and Techs for their excellent work. </li>
<li>  <a href="https://logbooks.jlab.org/entry/4443108"> A message </a> from Heidi regarding the SHMS valve 6 alarm: Please don’t call the Engineer-on-Call if valve 6 in the SHMS DI system alarms. This is a known issue, and the system should continue to function properly. </li>
<li> After that, we were smoothly collecting data for the z=0.67 kinematic until 1:40 am when the MBE3H05 magnet power supply tripped due to <a href="https://logbooks.jlab.org/entry/4443589"> DC overcurrent</a>. </li>
<li> MCC attempted to recover the power supply overnight without success. This morning, the hall was fully surveyed, and placed under controlled access. The DC power <a href="https://logbooks.jlab.org/entry/4443752"> fixed </a> the problem around 11 am. Thanks for their work.</li>
<li> We are planning to do a Moller polarization measurement on the coming Monday. </li>
<li> We will continue executing the <a href="https://hallcweb.jlab.org/wiki/images/4/45/R_SIDIS_Run_Plan_Summer_2025_JLab_v27.pdf"> Run plan </a>. </li>
<li>Here are the last three shift summaries from <a href="https://logbooks.jlab.org/entry/4443028"> yesterday's day </a>, <a href="https://logbooks.jlab.org/entry/4443275"> yesterday's swing </a>, and <a href="https://logbooks.jlab.org/entry/4443539"> and today's owl </a>. ABU for last 24 hours – 7.6 hours. Actual Beam in the Hall 10.6 hr.</li>

<li> <FONT COLOR=" #ff0000"> We have a few open shifts next week. Please sign up if you can. <a
