Status Report From: Goddard Space Flight Center
Posted: Monday, September 24, 2001

This morning at 1038 UT a powerful X2.6 solar flare erupted near the large sunspot 9632. A radiation storm (currently S2-class) is in progess and intensifying.The explosion also hurled a lopsided halo coronal mass ejection (CME) into space. The Earth-directed CME, pictured right in a SOHO coronagraph animation, will sweep past our planet late Tuesday or Wednesday and probably trigger geomagnetic storms. Stay tuned for updates.
