Edmonton's northern latitude (53.5°N) makes it one of Canada's better large cities for aurora, with displays visible from the city outskirts during Kp 4–5 storms and spectacular shows from dark sites nearby. Elk Island National Park, just 35 minutes east, is a Dark Sky Preserve with Bortle 3 conditions, and the vast Alberta prairie darkens rapidly in every direction. Jasper's world-renowned Dark Sky Preserve is a few hours west. The cold, dry continental climate brings long winter nights and superb transparency.
