SKYWATCHING -- Tonight might be prime time, if you can swing it, to go high away from city lights and above the clouds to watch the expected light show in the northern sky.
A massive explosion on the sun's surface has triggered the largest solar radiation storm since 2005, unleashing a torrent of charged plasma particles toward Earth.
The bad news: Could cause trouble with satellites and GPS navigation, power grids and other high-tech hardware.
The good news: Likely will trigger displays of aurora borealis, a.k.a the northern lights.
Predicting shows of northern lights is much the same for scientists as predicting the weather, since the aurora is a result of space weather.
While this week is special, scientists expect higher than normal solar activity to persist through the year. Scientists say there's been a minimum rate of solar and aurora activity since 2007.
