Partial-halo CME to deliver glancing blow on June 23

Filament eruption in the SSE quadrant of the Sun produced a partial-halo Coronal Mass Ejection (CME) first observed in coronagraph imagery near 08:45 UTC on June 19 (above). WSA-Enlil model suggests a glancing blow early on June 23. Beta-Gamma-Delta classified Region

M1.3 solar flare ejected, CME arrives on June17th

On June 14th around 08:10 UTC, a magnetic filament near the sun's eastern limb became unstable and erupted. The resulting blast hurled a bright and massive CME into space: The expanding cloud was observed by 3 spacecraft: STEREO-A, STEREO-B and SOHO....
