Northern Lights Forecast Over Canada
Skywatching Conditions
You may witness the Aurora Borealis dancing across the sky above. A volatile region of the Sun, prone to flares and solar storms, is leading to intense space weather in the upcoming nights.
Recent Solar Activity
Over the past weeks, solar eruptions have been observed, mostly on the Sun's side away from Earth or aimed away from us. All eruptions are linked to Active Region 4274, which has recently rotated into view along the Sun’s eastern limb.
Sunspot Activity and Solar Eruptions
The Sun's center image, captured by NOAA’s GOES-19 satellite’s SUVI instrument, shows bright active regions as of November. Near the middle, a darker area indicates a large coronal hole.
Four inset images from NASA/ESA’s SOHO spacecraft reveal four significant coronal mass ejections (CMEs) linked to AR 4274, highlighted in yellow.
Recent Solar Flare
On November 4, AR 4274 produced a powerful X1.8-class flare, the strongest since the X1.9 flare on June 19. It is the fifth strongest flare of 2025 so far.
Author's Summary
The Sun's active regions and recent solar flares, including a major X-class event, indicate increased space weather that may lead to visible auroras over Canada tonight.
