CHANCE OF FLARES: NOAA forecasters say there is a 25% chance of M-class solar flares today. With 8 numbered sunspot groups on the solar disk, a flare could come from almost anywhere. The most likely source would be fast-growing sunspot AR3081, which is nearly facing Earth.
BREAKING WAVE: Yesterday in the core of sunspot AR3078, an S-shaped strand of magnetism erupted. What happened next was a little unusual. A blast wave shot out sideways and broke against the wall of a nearby coronal hole:
Coronal holes are voids in the sun’s atmosphere where magnetic fields open up, allowing solar wind to escape. The hole’s nearly vertical magnetic walls and outflowing stream of solar wind stopped this blast in its tracks.
The S-shaped filament, called a “sigmoid,” re-formed after the explosion. Sigmoids are notoriously unstable, so more eruptions may be in the offing.
soon become a source of Earth-directed flares.
