UPDATED 10:47PM: So far tonight, the best viewing of the aurora has stayed in the New England states and in Canada. There's the outside chance that we could catch a glimpse late tonight, but it doesn't appear to be as active as the one was a few months ago. Here's a couple sites that try to predict within the hour, when the aurora might be visible.
UPDATED 7:00PM: Tonight, the aurora borealis (northern lights) may be visible to portions of the northeast, even into the Mid-Atlantic under perfect conditions. Last year, the northern lights were seen by numerous viewers in our area. It was a faint red and green, and is best seen in rural areas away from the city lights. Don't cancel plans tonight to go see it, but the chances are better tonight than they have been in several months.
WHAT CAUSES IT
On Sunday, a large solar flare on the sun released a burst of particles for the sun's atmosphere. According to NASA, it's headed toward the earth at 1,400 miles per second.
