Massive Solar Flares - Possible Auroras

[Mike]

A remarkable sunspot is crossing the face of the Sun. The large active
region stretches 15 Earth-diameters from end-to-end and poses a threat for
powerful flares.  Indeed, on July 15th, twisted magnetic fields above the
spot erupted.  The explosion sparked an X-class solar flare and hurled a
coronal mass ejection into space.  As a result, sky watchers on Earth
might spot auroras on Tuesday or Wednesday night.  Visit spaceweather.com
