On August 1st around 0855 UT, Earth orbiting satellites detected a C3-class solar flare. The origin of the blast was sunspot 1092. At about the same time, an enormous magnetic filament stretching across the sun’s northern hemisphere erupted. NASA’s Solar Dynamics Observatory recorded the action. A coronal mass ejection (CME) produced by the event is heading directly for Earth: SOHO movie. High-latitude sky watchers should be alert for auroras when it arrives on or about August 3rd.
In short, we have just witnessed a complex global eruption involving almost the entire Earth-facing side of the sun.
