Summary of the past 24 hours:
The beam stability has been pretty good, with only 1 significant downtime incident from the accelerator side. One RF zone dropped out of HV and an expert had to come from offsite to fix it - only 1 hour was lost because of this. In total, we have collected about 2.7B triggers on the helium target over the past 24 hours (4PM Saturday - 4PM Sunday). There are no changes to the plan to report - we will just continue collecting production data on the helium target at least until Monday, most likely longer. 

Issues:
*Overnight there were 2 instances where the shift crew noticed DAQ issues. Sergey was called both times. The first issue was resolved in about 20 minutes after re-setting the DAQ a few times. The second issue occurred at 4:15AM, and Sergey had to come into the counting house to address an issue with gluonraid3 (many thanks to him for coming in so early). The total time lost from this issue was about 1.5hrs.
*Mark Dalton identified 3 FCAL bases which may need to be replaced during the next access (https://logbooks.jlab.org/entry/4049856). He also restarted the BCAL LED pulsing script which had apparently stopped switching sides at some point since the start of the maintenance day Thursday morning (https://logbooks.jlab.org/entry/4049855).
