X-Class Solar flare heading our way!

The sun fired off a medium-strength flare on Tuesday (Sept. 9), then followed up with an Earth-directed X-class flare — the most powerful type — on Wednesday evening (Sept. 10). Both storms erupted from a sunspot known as Active Region 2158, which will be the focus of a webcast hosted today at 1 p.m. EDT (1700 GMT) by the online Slooh Community Observatory on its website:  www.slooh.com.

This storm will not be a direct hit - although it could disrupt some power lines and maybe kill a few satellites!
