Northern Lights put on a show across Canada, U.S., and parts of Europe
A rare geomagnetic storm is lighting up Canadian skies this week
Skywatchers were treated to a colourful display of the Northern Lights on Tuesday night, with vibrant flashes visible across Canada, the U.S., and even parts of Europe.
An even more intense aurora event is anticipated for Wednesday, potentially creating one of the most impressive displays of the year.

A rare G4 geomagnetic storm watch has been issued for Wednesday, a severe storm category according to the National Oceanic and Atmospheric Administration (NOAA). These significant events occur only a few times per year.
The peak period for Wednesday's aurora activity is expected between 10 a.m. and 2 p.m. EST, but there will likely be a strong G3 showing after the sun sets, then continuing into the overnight. Viewing conditions will depend on cloud cover and local weather.
This G4 storm may push auroras as far south as northern parts of Alabama and Northern California in the U.S. Canadians in western regions and the Prairies will have the best chance to witness the aurora due to clearer skies. Unfortunately, Eastern Canada will see poorer viewing conditions because of active weather systems over the Great Lakes and Atlantic Canada.
