RHIC Startup:

Blue Landau cavities were turned on, curing the dancing bunch problem.
Communication problems with a flakey chipmunk that had to be replaced, and a cryo temperature reading at 4OClock.
Ran a 6x6 fill for a STAR vertex check.  Vertex is consistent with being good, but RMS of vertex is so broad (70cm) that it is impossible to determine the vertex with any precision.
There is a tune jump at the start of the Blue ramp when in replay mode.  This will need to be addressed.
