AR 4366 is turning toward Earth

On 02/03/2026 10:28 am by Victor Rogus | Website | Sedona, Arizona, USA

The most active sunspot of Solar Cycle 25 (AR 4366) is turning toward Earth.
Sunspot 4366 is growing very rapidly and poses a threat for X-class solar flares.
This sunspot is just getting started. It has an increasingly unstable delta-class magnetic field, and it is rapidly adding new intermediary spots. More X-flares are likely in the days ahead,

103mm Jagers refractor, Badder Planetarium safety prism, using neutral tensity and a solar continuum filter, Losmandy GM-8 mount. Cannon 60Da camera. 650 FL 12.5 mm eyepiece.
