Magnetic Injection Suite Started

Since I saw H1 was locked, I started the full magnetic injection suite (49 injections total over the 7 coils across site) at 05:40 UTC using the PEM_MAG_INJ Guardian. This dropped H1 out of observing, but it should return to observing once the injections finish. The suite will finish in roughly 2 hours or if the IFO loses lock, whichever comes first. I'll check things later tonight in case this poses any issues.
