Friday evening is looking like it害羞草研究所檚 going to be a good night to see the northern lights, even if you don害羞草研究所檛 happen to be in the north.

Canada害羞草研究所檚 space weather agency is warning of a 害羞草研究所渕ajor geomagnetic storm害羞草研究所� 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 害羞草研究所渟pectacular, colourful display of light commonly seen in the night sky in the northern hemisphere.害羞草研究所�

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 害羞草研究所減otentially historic event.害羞草研究所�

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害羞草研究所檛 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.

害羞草研究所淔or most people here on planet Earth, they won害羞草研究所檛 have to do anything,害羞草研究所� said Rob Steenburgh, a scientist with NOAA害羞草研究所檚 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.

害羞草研究所淭hat害羞草研究所檚 really the gift from space weather 害羞草研究所� the aurora,害羞草研究所� 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 害羞草研究所渢here might be actually a nice little treat there for you,害羞草研究所� 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. 害羞草研究所淲e are not anticipating that害羞草研究所� but it could come close, said NOAA space weather forecaster Shawn Dahl.

This storm 害羞草研究所� ranked 4 on a scale of 1 to 5 害羞草研究所� poses a risk for high-voltage transmission lines for power grids, not the electrical lines ordinarily found in people害羞草研究所檚 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 害羞草研究所� known as a coronal mass ejection 害羞草研究所� can contain billions of tons of plasma and magnetic field from the sun害羞草研究所檚 outer atmosphere, or corona.

The flares seem to be associated with a sunspot that害羞草研究所檚 16 times the diameter of Earth, according to NOAA. It害羞草研究所檚 all part of the solar activity that害羞草研究所檚 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害羞草研究所檚 science satellites. Extremely sensitive instruments will be turned off, if necessary, to avoid damage, said Antti Pulkkinen, director of the space agency害羞草研究所檚 heliophysics science division.

Several sun-focused spacecraft are monitoring all the action.

害羞草研究所淭his is exactly the kinds of things we want to observe,害羞草研究所� Pulkkinen said.
