Dazzling Auroras Predicted to Illuminate Canadian Skies This Thursday Night

Skywatchers across Canada should prepare for a spectacular display of auroras this Thursday night. A series of slow-moving solar storms are expected to illuminate the skies, thanks to three coronal mass ejections (CMEs) that erupted from the Sun over the recent Thanksgiving long weekend.

Dazzling Auroras Predicted for Canadian Skies

The NOAA’s Space Weather Prediction Center has issued a G2 geomagnetic storm watch for October 16. This alert is due to the anticipated effects of the solar storms on Earth’s geomagnetic field. These CMEs all originate from Active Region 4246, which is currently crackling with numerous solar flares, including several moderate M-class flares.

Details on the Solar Activity

As Active Region 4246 approaches the Sun’s western limb, it remains in view of satellite observation. This means that even minor flares and CMEs could still have significant impacts here on Earth. The sunspot cluster has nearly three dozen individual sunspots, revealing its volatile nature through a tangled arrangement of positive and negative magnetic polarities.

What to Expect

• The first CME possibly reached Earth early on October 15 but had a minimal impact.
• The second CME is expected to arrive later on October 16, likely amplifying the effects.
• This combination may trigger a G2 (moderate) geomagnetic storm in the evening.
• A G1 (minor) storm level is anticipated overnight into Friday morning.

In conclusion, be ready to look up and witness the stunning auroras that may cascade across the skies of Canada this Thursday night. The celestial light show promises to be a thrilling spectacle for both amateur and seasoned observers alike.
