Comments: Shift started in controlled access, which consumed most of the first hour. This was to put the lumi back in the DAQ and to fix the RICH detector. During the second hour (17:00-18:00), there was a loss of communication with the left HRS magnets and detectors, resulting in an IOC reboot which also required a power-cycling of the left dipole NMR. After the second hour, it was smooth data taking for the next six hours
