This morning, Jan 23rd a solar flare reaching M8.7 ( M.9 confirmed by spaceweather.com) was generated by Active Region 11402 at 03:59 UTC Monday morning. R2 Radio Blackout, 100 MeV Proton Spike and 10cm Radio Burst resulted. As well as a 10cm Radio Burst (TenFlare) which lasted 19 minutes was also reported.
A Full-Halo Coronal Mass Ejection (CME) followed immediately after this event, with components appearing to be Earth directed. The main bulk of the incoming plasma cloud appears to be directed above the Earth however impact is estimated to arrive during Jan 25-26
The explosion’s M9-ranking puts it on the threshold of being an X-flare, the most powerful kind.
Analysts at the Goddard Space Weather Lab say the leading edge of the CME will reach Earth on Jan. 24 at 14:18UT (+/- 7 hours).
Their animated forecast track shows that Mars is in the line of fire, too; the CME will hit the Red Planet during the late hours of Jan. 25.
