Sunspot exploding

Received this email from Spaceweather:

Solar activity has suddenly increased with a series of strong explosions from sunspot 786, including an X-category flare this morning. Because the sunspot is near the sun's western limb, none of the blasts was squarely Earth-directed. Nevertheless, coronal mass ejections hurled into space by these explosions could deliver glancing blows to Earth's magnetic field as early as tonight (July 14-15) and continuing through the weekend, possibly sparking geomagnetic storms and auroras. Check spaceweather.com for movies of the explosions, more information and updates.
