Analysis of Extreme CMEs and Their Energetic Events (1998-2011)

DESCRIPTION

This report examines extreme coronal mass ejections (CMEs) with a focus on 4-sigma and 3-sigma events recorded from 1998 to 2011. Notable events such as those on February 1, 2003, and September 7, 2011, are highlighted. The study provides a statistical comparison of these extraordinary CMEs to the overall CME sample, addressing mass and kinetic energy distributions. A power-law distribution is observed for CMEs with energies exceeding 1e30 ergs, indicating a complex behavior in the most energetic solar events.

  1. Extreme CMEs (Energies) Emech > 4 sigma: 4 events Emech > 3 sigma: 21 events 1998-05-06 1999-06-23 2001-04-02 2002-01-18, 03-17, 06-11, 11-01,12-28 2003-02-01, 02-18, 04-27, 06-01, 10-29, 11-03, 11-18 2004-01-22 2005-02-23 2006-11-21 2008-12-27 2009-07-20 2011-09-07 2003-02-01, 10-29 2006-12-08 2009-07-20 Vourlidas

  2. Example: Oct-Nov 2003 Events 2657 W70 < Lon < W90 1420 827 1136 1406 E90 < Lon < E80 1085 (http://beauty.nascom.nasa.gov/~ptg/oct-nov-2003-xflares.html) Vourlidas

  3. How Unusual Are These Events? • Comparison to full CME Sample • Masses at the 1-5 % of all events • Kinetic Energy at < 1% of all events Vourlidas

  4. Total Mechanical Energy Distribution of CMEs (1996-2011) Conclusions: Emax < 1e33 ergs. Power-law distribution for CME> 1e30 ergs (a=-2.3). P=1e-6 for E~8e33 ergs. Vourlidas
