NASA models using data from the Solar Terrestrial Relations Observatory (STEREO) and the Solar Heliospheric Observatory (SOHO) have now provided more information about the two Coronal Mass Ejections (CME) associated with the two March 6 flares. Such a CME could result in a severe geomagnetic storm, causing aurora at low latitudes, with possible disruption to:
- high frequency radio communication - global positioning systems (GPS) - power grids. The models also predict that the leading edge of the first CME will reach Earth at about 1:25 AM EST on the morning of March 8 (plus or minus 7 hours) and the event may last 3 days.
The first CME is traveling faster than 1300 miles per second; the second more than 1100 miles per second. NASA's models predict that the CMEs will impact both Earth and Mars, as well as pass by several NASA spacecraft.
