Eruptions like Tuesday's X-class flare will only become more common.
09 August 2011, 12:18 PM ET
A comprehensive look at the different classes associated with Sun flares and the impact they have on Earth. Includes footage of the most powerful flare recorded.

The X6.9-class solar storm rocked the sun early Tuesday (Aug. 9).
09 August 2011, 10:11 AM ET
The Aug 9, 2011 eruption on the Sun that produced a X-7 class flare caused a temporary blackout of high frequency radio transmissions on the side of Earth covered in daylight. Navigation signals can be degraded in these instances.

A solar storm may spark auroras as far south as Pennsylvania, NASA says.
05 August 2011, 12:11 PM ET
A double whammy of coronal mass ejections occurred on our star, less than 2 hours apart, on August 3rd. Solar winds may carry these super-heated particles towards Earth; a glancing blow causing auroras and possibly damaging satellites.
