The Sun’s Long-Lived Active Regions Are Massive Flare Factories—But We Don’t Know Why Space weather is a fascinating subject, but one we still have a lot to learn about. One of the main components of it is the active regions (ARs) of the Sun. These huge concentrations of magnetic fields show up throughout the Sun’s photosphere and are the primary source of solar flares and coronal mass ejections (CMEs). They can be simple pairings of magnetic flux or huge, magnetically complex tangles that spend weeks creating massive solar storms before dissipating. But tracking the longest lived of these ARs has been a headache for solar physicists, and a recent paper by Emily Mason and Kara Kniezewski, published in The Astrophysical Journal, both dives into this tracking problem and uncovers some interesting features of the Sun’s most persistent ARs.

Eclipse Study Tracks Turbulence Through the Solar Corona It was an amazing sight witnessed by many during the April 2024 total solar eclipse. For a few precious moments, it seemed like a celestial dimmer switch was thrown, as the Moon eclipsed the Sun. It was one of the very few times you could actually see prominences and the pearly white corona of the Sun in person, without the aid of special equipment. Now, a recent study out of the University of Hawai’i has linked high resolution images taken during totality with observations from missions orbiting the Sun, in an effort to chronicle the evolution of space weather.

This study documents the findings in a case of solar retinopathy, 6 days after sungazing. A malignant melanoma of the choroid was diagnosed in a 65-year-old man. On fundoscopy, the macula was normal. The patient agreed to stare at the sun prior to enucleation. A typical solar retinopathy developed, characterised by a small, reddish, sharply circumscribed depression in the foveal area
