Northern Lights Fade as Sun Enters Quieter Phase
7 Apr
Summary
- Northern lights displays in southern Canada will become rarer.
- The sun is moving from a solar maximum to a less active phase.
- Northern territories remain prime viewing spots for auroras.
The vibrant auroral displays, which have occasionally illuminated the skies of southern Canada with vivid colors, are expected to diminish. This change is due to the sun's natural 11-year cycle, as it moves away from its peak activity period, known as the solar maximum. While the past two years offered prime viewing conditions, the sun is now entering a less active phase, projected to reach its minimum around 2031.
Consequently, the frequency of aurora sightings in southern parts of Canada, including areas like Ontario and British Columbia, will decrease. However, the northern Canadian territories of the Northwest Territories, Yukon, and Nunavut will remain prime locations for experiencing the northern lights. These regions are situated within the auroral oval, where these celestial phenomena are visible almost nightly, regardless of the sun's current activity level.
Tourism in these northern areas has benefited from the recent solar maximum. For instance, Tourism Yukon actively promoted the northern lights as a draw for international tourists from the UK, Germany, Switzerland, and Australia. Similarly, the Northwest Territories reported that approximately 41 percent of tourists were attracted by the aurora, with Yellowknife alone experiencing up to 240 nights of visible lights annually. While the waning solar activity may impact future tourism strategies, these northern regions will continue to be top destinations for aurora viewing.
