Re: the slumber is over

GREAT FILAMENT: The Solar and Heliospheric Observatory (SOHO) is tracking an enormous magnetic filament on the sun. It stretches more than one million kilometers from end to end, which makes it an easy target for backyard solar telescopes. Readers with iPhones can inspect the filament in 3D. (Hint: In the app, tap the "Wavelengths" tab and select the orange sun.)
