    16:00 No beam, beam should resume at around 6PM but going to power permit

    Calorimeter LED scan

    Taking cosmics data

    19:15 Beam into the hall on empty target, start checking beam properties

    19:20 MCC has some RF problems beam delivery delayed for a couple of minutes

    19:40 MCC working on the orbits

    20:45 Beam into the hall, a bit off in Y position Y=2mm

    20:50 beam steered to 1.4 mm in Y but beam unstable waiting to make
    harp scan

    20:20 beam looks good and is stable moving to LH2 target to make
    two arms run

    21:30 Moving to optics target

    21:50 Moving back to 15cm LH2 target for DVCS data taking
    while beam is unstable

    22:40 RF lost in one part of the accelerator, no beam for at least
    30 mins
    Testing LED proton configuration... seems not to work...

    23:05 Beam back

    asked for Bleedthrough measurement but did not got it yet ( shift change I guess and beam unstable)

    No Compton Data yet since beam was not very stable
