RHIC Running:  There was colliding Au beam at 9 GeV/n in both PHENIX and STAR last night.  STAR received their goal of 5000 good events.  PHENIX was also satisfied with the beam delivered to them.  By 10:30PM Todd was beginning to tune up 5 GeV/n Au beam.  Au beam was brought to AGS Extraction.  At 02:30 there was a Quench Link Interlock in b4-dh0 which resisted attempts by CAS to fix it.  Finally a card was replaced to allow Blue to ramp without b4-dh0 (which unfortunately shares a power supply with the DX magnet required for Yellow Beam) around 06:00AM.  By 10:00AM Au beam at 5 GeV/n had been sent half way around the Yellow ring.  There was no morning meeting this morning to allow Todd to continue Low Energy development.
