Friday evening is looking like it含羞草研究社檚 going to be a good night to see the northern lights, even if you don含羞草研究社檛 happen to be in the north.

Canada含羞草研究社檚 space weather agency is warning of a 含羞草研究社渕ajor geomagnetic storm含羞草研究社� hitting the country tonight.

Not only could it have severe impacts on power systems and other infrastructure, but it could result in the aurora borealis being visible well into the southern U.S.

Space Weather Canada refers to the northern lights, or aurora borealis, as a 含羞草研究社渟pectacular, colourful display of light commonly seen in the night sky in the northern hemisphere.含羞草研究社�

The Weather Network is reporting that the best spots to catch a glimpses tonight will be the western Prairies and into British Columbia, with the best time to catch the illuminated skies in B.C. between 8 p.m. and 2 a.m. Saturday.

Space Weather Canada says the lights are a product of massive solar flares was striking all of Canada Friday afternoon.

The U.S. National Oceanographic and Atmospheric Administration issued its first geomagnetic storm watch since 2005 and says the storm is a 含羞草研究社減otentially historic event.含羞草研究社�

A spokesman for electricity provider BC Hydro says it has been preparing for the storm, and such events can potentially cause serious damage to high-voltage transmission systems, leading to outages.

Kevin Aquino says while those effects aren含羞草研究社檛 expected, BC Hydro staff are monitoring for any impacts.

Space Weather Canada says the storm warning will be downgraded late Friday to a storm watch that will last until Saturday afternoon.

It says major storm activity is associated with very high risk of affects on geostationary satellites, and potential severe disruption to activities involving geomagnetism, including aerial surveys and directional drilling.

The storm could also extend the northern lights across all of Canada and as far south as California.

NOAA alerted operators of power plants and spacecraft in orbit to take precautions, as well as the Federal Emergency Management Agency.

含羞草研究社淔or most people here on planet Earth, they won含羞草研究社檛 have to do anything,含羞草研究社� said Rob Steenburgh, a scientist with NOAA含羞草研究社檚 Space Weather Prediction Center.

The storm could produce northern lights as far south in the U.S. as Alabama and Northern California, according to NOAA. But it was hard to predict and experts stressed it would not be the dramatic curtains of color normally associated with the northern lights, but more like splashes of greenish hues.

含羞草研究社淭hat含羞草研究社檚 really the gift from space weather 含羞草研究社� the aurora,含羞草研究社� said Steenburgh. He and his colleagues said the best aurora views may come from phone cameras, which are better at capturing light than the naked eye.

Snap a picture of the sky and 含羞草研究社渢here might be actually a nice little treat there for you,含羞草研究社� said Mike Bettwy, operations chief for the prediction center.

The most intense solar storm in recorded history, in 1859, prompted auroras in central America and possibly even Hawaii. 含羞草研究社淲e are not anticipating that含羞草研究社� but it could come close, said NOAA space weather forecaster Shawn Dahl.

This storm 含羞草研究社� ranked 4 on a scale of 1 to 5 含羞草研究社� poses a risk for high-voltage transmission lines for power grids, not the electrical lines ordinarily found in people含羞草研究社檚 homes, Dahl told reporters. Satellites also could be affected, which in turn could disrupt navigation and communication services here on Earth.

An extreme geomagnetic storm in 2003, for example, took out power in Sweden and damaged power transformers in South Africa.

The sun has produced strong solar flares since Wednesday, resulting in at least seven outbursts of plasma. Each eruption 含羞草研究社� known as a coronal mass ejection 含羞草研究社� can contain billions of tons of plasma and magnetic field from the sun含羞草研究社檚 outer atmosphere, or corona.

The flares seem to be associated with a sunspot that含羞草研究社檚 16 times the diameter of Earth, according to NOAA. It含羞草研究社檚 all part of the solar activity that含羞草研究社檚 ramping up as the sun approaches the peak of its 11-year cycle.

NASA said the storm posed no serious threat to the seven astronauts aboard the International Space Station. The biggest concern is the increased radiation levels, and the crew could move to a better shielded part of the station if necessary, according to Steenburgh.

Increased radiation also could threaten some of NASA含羞草研究社檚 science satellites. Extremely sensitive instruments will be turned off, if necessary, to avoid damage, said Antti Pulkkinen, director of the space agency含羞草研究社檚 heliophysics science division.

Several sun-focused spacecraft are monitoring all the action.

含羞草研究社淭his is exactly the kinds of things we want to observe,含羞草研究社� Pulkkinen said.
