High-speed electron and atomic-nucleus streams {solar prominence} {solar flare}| arch from chromosphere into inner corona, up to 400,000,000 meters high and 50,000,000 meters wide, for up to 30 minutes. Solar flares can make x-rays. Sunspots and solar flares can have large plasma ejections {coronal mass ejection} (CME).
