For some unknown reason the breaker for the Septum magnet Danfysik power supply tripped off. It is breaker 14 on the SB ESA panel. This is the panel against the wall of the hall, feeding most of the AC power to the hall. We reset the breaker and the Danfysik was brought back up. It seemed to be OK, so we set the current and left the hall. If the breaker trips again tonight, the magnet is to be left turned off until it can be looked at during the day.
