    Summary
    =======
    00:00 Start shift in Controlled Access to fix LHRS IOC problem.
    00:15 IOC problem fixed, asked for beam permit.
    00:30 Beam back. Raster off.
    00:35 Resume production running.
    00:54 Change RHRS momentum setting to 2.81464 GeV/c.
    00:59 Change LHRS momentum setting to 2.87093 GeV/c.
    01:13 Change LHRS momentum setting to 2.81464 GeV/c.
    01:36 Change LHRS momentum setting to 2.75835 GeV/c.
    01:56 Change RHRS momentum setting to 2.70206 GeV/c.
    01:58 Change LHRS momentum setting to 2.70206 GeV/c.
    02:19 Change LHRS momentum setting to 2.67660 GeV/c.
    02:25 Move to Loop 3 LH2 target.
    02:27 Raster back on.
