[47.02] Active Region Evolution and Activity During the Storms of Halloween 2003

P. T. Gallagher (NASA Goddard Space Flight Center/L-3 Com GSI)

The three week period around Halloween 2003 was characterized by some of the largest and most energetic flares and CMEs observed in recent years (e.g., see http://beauty.nascom.nasa.gov/~ptg/oct-nov-2003-xflares.html for details of the 12 X-class flares). This increased activity resulted from the almost simultaneous formation of three complex beta-gamma-delta regions: NOAA 0484, 0486, and 0488. In this talk, the distinctive characteristics, rapid evolution, and extreme activity of the these regions will be reviewed in light of the multitude of observations from SOHO, RHESSI, TRACE, BBSO, and other ground- and space-based observatories. Our current understanding of the mechanisms involved in forming such regions, and the processes involved in storing and releasing such numerous and energetic events will also be discussed.
