MC1 <--> MC3 |

About 30mins ago, I saw another glitch on MC1 - this happened while the Watchdog was shutdown.
In order to further narrow down the cause of the glitch, we switched the Coil Driver Board --> Satellite box DB(15?) connectors on the coil drivers between MC1 and MC3 coil driver boards. I also changed the static PIT/YAW bias voltages to MC1 and MC3 such that MC-REFL is now approximately back to the center of the CCD monitor.
