ARTCC RADAR CTLR CLAIMS LR25 PENETRATED THE MOA AT FL215. CHARTS INDICATE THE MOA GOES UP TO BUT NOT INCLUDING FL180. CONFERRING WITH SUPVR ADVISED NO ACTION WOULD BE TAKEN.

Narrative

WE WERE ON AN ASSIGNED HDG TO JOIN THE 312 DEG RADIAL OFF OF MFE APPROX 175 DEGS TO JOIN. TO MAINTAIN FL240 UNTIL ON THE 312 DEG RADIAL THEN DSND TO 11000 FT. MY HSI INDICATED THAT WE WERE JOINING THE RADIAL; SO I BEGAN A GENTLE TURN AND INITIATED DSCNT. UPON REACHING (PASSING) THROUGH 21500 FT MSL ATC QUERIED ME. WHEN I ADVISED ATC THAT I WAS DSNDING AS I WAS ON THE RADIAL; HIS RESPONSE WAS 'NEGATIVE.' A FEW SECONDS LATER HE JUST SAID 'CONTINUE THE DSCNT; YOU'VE PENETRATED THE MOA.' I SPOKE WITH THE SUPVR ONCE ON THE GND. HE CHKED THE TAPES AND SPOKE WITH BOTH CTLRS. HE INDICATED THAT I WAS OFF COURSE; THERE WAS AN MOA PENETRATION AND THERE WAS NOT AN ACFT CONFLICT. HE (THE SUPVR) SAID THERE WOULD BE NO ACTION TAKEN; BUT TO HAVE MY EQUIP CHKED. I DID A VOR CHK AND THE VOR WAS WITHIN TOLERANCES. I BEGAN MY TURN EARLY TO TURN IN TO JOIN THE 312 DEG RADIAL MFE. I MUST HAVE BEEN TOO SOON AND WILL IN THE FUTURE WAIT UNTIL THE NEEDLE IS ABSOLUTELY CTRED. I BEGAN MY TURN EARLY; AS WE WERE TRAVELING AT 460 KTS GS.
