swc.gsfc.nasa.gov - On March 2nd, 2012, active region 1429 rotated onto the Earth-facing solar disk. This region has dominated space weather conditions throughout the solar system for more than three weeks, a little shy of one solar rotation (about 27 days).
During the period of March 2nd to 15th, it rotated across the solar disk and fired off more than 50 flares! The M-class flares from this active region that occurred on March 4th, 9th, 10th and13th were dramatic as well. On March 16th, the active region finally rotated off the Earth-facing solar disk. When features on the Sun move behind the Earth-facing solar disk, and the action continued with four events on the backside of the Sun. The long-lasting nature of its activities may give us a new glimpse into the inner workings of solar activities that are the major and ultimate source of space weather.
