Northern Lights Forecast to Shine Over Canada Thursday Night
The Aurora Borealis may light up the Canadian skies once again. A highly active region on the Sun, crackling with solar flares and releasing waves of energy into space, is generating conditions for strong auroras in the coming nights.
In recent weeks, solar astronomers and space weather experts have observed a remarkable sequence of eruptions from the Sun. These events, known as coronal mass ejections or solar storms, mostly occurred on the far side of the Sun or moved away from Earth. However, they all originated from a single cluster of sunspots identified as Active Region 4274, which has recently rotated into view along the Sun’s eastern limb.
Solar Observations and Imagery
The Sun’s latest activity has been captured in stunning detail. The SUVI instrument aboard NOAA’s GOES-19 weather satellite shows several bright active regions as of early November. Near the image center appears a darker area marking a large coronal hole.

Powerful Solar Flare from AR 4274
On the morning of November 4, AR 4274 produced a major explosion — an X1.8-class solar flare. This eruption is the most powerful since the X1.9 flare on June 19 and currently ranks as the fifth strongest solar flare of 2025.
Potential Impact
- Enhanced auroral activity visible across parts of Canada.
- Possible short-term disruptions to satellite communications.
- Increased visual opportunities for skywatchers during clear conditions.
Author’s Resume: Solar activity from AR 4274 may trigger visible northern lights over Canada, bringing vibrant auroras and heightened geomagnetic conditions this week.
