Asymmetric, Earth-directed partial-halo CME and M1.0 solar flare erupted from Region 2497

An asymmetric partial-halo Coronal Mass Ejection (CME) erupted from Region 2497 late February 11, 2016. The CME was, at least in part, produced by a long duration C8.9 solar flare that peaked at 21:03 UTC. Associated with the event were Type II and Type IV radio...

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...
