<b>Accelerator Status:</b>
<ul>
  <li>Jan 28 Day/Swing (yesterday):
    <ul>
      <li> Very good beam throughout Day and Swing.  <a href="https://logbooks.jlab.org/entry/3978361">Day Beam Summary</a>, <a href="https://logbooks.jlab.org/entry/3978555">Swing Beam Summary</a></li>
    </ul>
  </li>
  <li>Jan 29 Owl/Day (today):
    <ul>
      <li> Very good beam throughout Owl, and hopefully throughout day shift. <a href="https://logbooks.jlab.org/entry/3978725">Owl Beam Summary</a> </li>
    </ul>
  </li>
</ul>

<b>General Hall C Status:</b>
<ul>
  <li> Jan 28 Day/Swing (yesterday):
    <ul>
      <li> Very good beam quality which allowed us to complete Q2 = 5, W = 2.95, x = 0.39, low-epsilon, (SHMS Left) in early Owl. </a>
    </ul>
  </li>
  <li> Jan 29 Owl (today):
    <ul>
      <li> While changing kinematics to <b>Current Kinematic Setting</b>, HMS drive controller faulted. See log-entry <a href="https://logbooks.jlab.org/entry/3978611">HMS Drive Controller Fault </a> </li>
      <li>
	Long story short, we were not able to reset controller due to expert staff unavailability from both MCC and Hall C due to severe weather. Luckily for us, the HMS
	drive controller faulted right at 25.036 deg (almost at the run plan setting of 25.02).
      </li>
      <li> Resumed data-taking at this kinematics, and lucklily for us again, the rates were lower than expected from the plan, so we did not actually loose much time </li>
    </ul>
  <li> Jan 29 Day (today):
    <ul>
      <li> We will go into Controlled Access after today's 10 am RC Daily Meeting, for D. Gaskell to reset HMS Drive Controller and change to smaller SHMS angle. </li>
      <li> For a detailed run plan for today, please refer to: <a href="https://logbooks.jlab.org/entry/3978722">Jan 29 Day Shift Run Plan</a></li>
    </ul>
  </li>
</ul>

<b>Hall C PION-LT Data Collection/Analysis Status:</b><br>
<ul>
  <li>Jan 29 Owl (today):
    <ul>
      <li> We have reached ~100 % of LH2 data at Current Kinematic Setting. Then we'll take 1 hr-long of Al. Dummy data, and go back to LH2
      data-taking for additional statistics until we coordinate Controlled Access after the RC Daily meeting. </li>
      <li> <b>Current Kinematic Setting:</b> <br> Q2 = 2.45, W = 3.20, x = 0.21, low-epsilon, (SHMS Left), <br>  SHMS: 6.265 GeV/c, 8.16 deg <br> HMS: -1.644 GeV/c, 25.035 deg </li>
    </ul>
  </li>
</ul>
