Greetings,

 Hall C will wait until this afternoon to re-visit the fast dump of the magnets. Cryo has informed us that due to the CHL2 recovery this is no head room for a fast dump recovery. 

 One possibility is for Hall C to wait until Hall B does their fast dump, then Hall C does their highest TEST current fast dump immediately afterwards. This eliminates multiple hits to the recovery compressor. The Hall C fast dump is not expected to produce a large load. It will be noticeable but not a full energy dump. Sounds a little scary for cryo but this type of vent does occur during experimental runs, where one hall trips off another hall.
