I disconnected the heater at ~2:20 UTC, leaving the sensor circuit operational. Don't be fooled by the apparent railing of the heater in the monitor trace below---the heater has been physically disconnected, so there is no current flowing even though the servo is railed (since the error signal is huge with the loop open).

Kiwamu and I also restarted c1sus and locked the MC so that we can get some uncontrolled Stochmon data. I think he is planning to reconnect the heater some hours from now so that we can get yet another controlled data stretch (since the first one was cut short by c1sus's going down).
