GREAT FILAMENT: A vast filament of magnetism is cutting across the sun’s southern hemisphere today. Run a finger along the golden-brown line in this extreme UV image from the Solar Dynamics Observatory and your digit will have traveled more than 400,000 km.
A bright ‘hot spot’ just north of the filament’s midpoint is UV radiation from sunspot 1112. The proximity is no coincidence; the filament appears to be rooted in the sunspot below. If the sunspot flares, it could cause the entire structure to erupt.
UPDATE: Yesterday’s M3-flare did not destabilize the filament. Stay tuned, however, because sunspot 1112 is growing and more activity is possible in the hours ahead. Readers with solar telescopes are encouraged to monitor developments.
Yes, and it’s a beautiful day in Weather sKwirl country — so get out and enjoy!
