A small northern slice of the United States could get a rare glimpse of the northern lights on Thursday (Dec. 10) night.

A geomagnetic storm may cause the lights, or aurora borealis, to dip more southward than usual, according to Space Weather Watch. Earlier this week, there was hope that the northern lights might dip well into the United States, with aurora visible as far south as New England and Chicago, but now it appears that the best views will be within Canada and perhaps around the U.S-Canada border.

The aurora borealis (and their cousins in the Southern Hemisphere, the aurora australis) are caused by the solar wind, a stream of charged particles that emanates from the sun and interacts with Earth's upper atmosphere.These charged particles excite oxygen and nitrogen molecules in the atmosphere. As the molecules return to their regular state, they emit particles of light called photons. These photons create the ghostly, dancing colors that make up the aurora.

Typically, the lights appear only near the poles. But when the geomagnetic disturbance to the atmosphere is particularly strong, they can appear at lower latitudes. The National Oceanic and Atmospheric Administration (NOAA) maintains a 30- to 90-minute forecast of the aurora, providing the most up-to-date predictions of who might be able to view the phenomenon.

1. Well, shoot. Although, it's supposed to be cloudy here in Michigan anyway.

2. i'm going to be watching for it...

Just in case. Haven't seen it for a while but it could be visible here in Montana so I'll watch for it since it's clear tonight.

We're getting all kinds of celestial events to enjoy with this aurora possibility, the Jupiter/Saturn conjunction and for the next couple evenings a meteor shower.

PORTLAND, Maine -- An initially promising U.S. forecast for the northern lights has gone bust.

Stargazers in the continental 48 states have essentially zero chance of seeing the astronomical phenomenon this week, the head of operations at the U.S. government's space weather prediction center said Thursday.

Curtains of color paint the night sky when the northern lights, or aurora borealis, are visible. Some early reports had suggested they would be viewable as far south as Illinois this week.

Robert Rutledge, the lead of operations at the Space Weather Prediction Center, said the agency had high hopes for Thursday and Friday, but it downgraded its forecast because the chances turned out to be a “big miss.”
