Giant Solar Blast Headed for Earth

The biggest solar blast in four years erupted late Monday, and it’s sending jets of charged particles right at Earth. The flare will spark bright auroras when it hits the magnetosphere in the next 24 to 48 hours.

A cluster of sunspots called Active Region 1158 unleashed the flare at 8:50 p.m. EST, Feb. 14 [1:50 a.m. UT, Feb. 15]. The flare was classified as a class X2.2, meaning it is the most powerful flare since December 2006. The sunspots have continued to let loose smaller flares and may still be active now.

NOAA forecasters estimate a 45 percent chance of geomagnetic activity on Thursday, Feb. 17, when the bulk of the radiation hits Earth’s magnetic field. It may create a stunning display of aurora borealis, better known as northern lights. So look up! If you take pictures, send us your best shots. If we get enough, we’ll create a reader gallery.
