    11:56 MCC calls to tell us they'll be down for "a few minutes" with a magnet problem. (Already back up and cycling). We just let run 1947 continue.
    12:06 still no beam. We end run 1947.
    12:22 Beam finally back. (MCC speak: "a few minutes" = half hour)
    12:34 MCC has RF problem. Have called someone in to check on it. Might only be "a few minutes".
    12:48 MCC says another 15-20 minutes.
