At 00:28 UTC on March 7 a major solar flare (X5 level) launched a Coronal Mass
Ejection toward earth. It is expected to begin impacting earth's
magnetosphere late in the day (UTC) on march 8 or early on March 9. If the
interplanetary magnetic field is in a south oriented position during the period
of its impact, the CME may cause extremely high levels of low altitude
ionospheric refraction. The field may begin "ringing" as the CME approaches.
In the past this has produced very strong but short duration propagation
effects on low frequency propagation. Be prepared to stay up all night to see
what happens on the top band. A hollow sounding effect on atmospheric noise
will alert you as things begin to get weird.
