SIZE MATTERS:AR1654 still has a little growing to do to take top honors in the bigness competition. However I only found two regions bigger in 2012. On July 13, AR1520 was a bloated Gigantor at 1460 Millionths; and on March 8, AR1429 grew to 1270 Millionths. Both of these were classified Beta-Gamma-Delta and both produced X-flares. There may be one or two others but I don't think so. ARs 1476 and 1515 were big, but less than 1100 millionths big.
