    16:00 Start shift without beam
    16:23 Beam back at 20uA
    16:23 Run 1190 started with HRSp at +2%
    17:00 Run 1190 stopped at 1M events (coincidence estimated to be 500K)
    17:00 HRSe changed to 1.06 GeV for white spectrum
    17:36 Run 1192 (1st run for white spectrum)
    18:09 Run 1193 (2nd run for white spectrum)
    19:35 Spectrometer change (see halog entry
    19:41 Both spectrometers ready
    19:41 New trigger downloaded

    20:27 MCC has RF problem. Beam off
    21:13 RF problem repared. Beam being restored.
    21:19 Run 1197 started (+4% of elastic)
    21:39 Run 1197 stopped
    21:39 HRSe (left) change to 2.189 GeV for +3% setting
    21:45 HRSe (left) stable for +3% setting
    21:45 Run 1198 started
