<h2>Accelerator and Hall Status</h2>
<ul>
  <li>The last 24 hours were very productive, we collected <b>1.46 C</b> on LH2!</li> 
  <li>Acc. had <b>93.75%</b> uptime! First time over 90% this year. <a href="https://logbooks.jlab.org/entry/4388139">https://logbooks.jlab.org/entry/4388139</a> </li>
  <li>DAQ was very stable, about 60% more efficient than usual.</li>
  <li>There has been a few instances of GEM layers tripping but each time the issue was resolved very quickly. Many thanks to Asar, the GEM expert on-call! </li>
  <li>In the last few runs (starting from 4273), we've observed fluctuations of approximately 10% in the coin match trigger rate. DAQ experts are aware of the issue and are actively investigating the underlying cause. As all diagnostic plots appear normal across the detectors, data taking is continuing as planned.</li>
</ul>
