(PhysOrg.com) -- Late in the evening on June 20 the sun emitted a long lasting C7.7 small class flare that peaked around 11:25p.m. EDT. A C-class flare is a relatively small flare.

The flare was associated with a (CME) that bloomed off the sun at 11:09p.m. EDT (0412 UT). The movie shown above was captured by the Solar and Heliospheric Observatory spacecraft.

Preliminary modeling shows the CME to be moving in Earth's direction at almost 500 mph (800 km/s). Geomagnetic effects and possible auroras on Earth should be moderate, appearing on June 23.

Thanks for the story.

We don't know why, . . . yet, but solar out bursts may be linked to solar slumber.

Like the ill temper of a bear in hibernation.

With kind regards,
