Huge Sunspot 4478

On 06/28/2026 09:42 am by Victor Rogus | Website | Sedona, Arizona, USA

This morning we see huge sunspot 4478 that has a 'beta-gamma-delta' magnetic field that harbors energy for X-class solar flares. Seen through wildfire smoke, from the nearby "Pocket" fire, as its called.

103mm Jaegers refractor, Baader Planetarium safety prism, using neutral density and a solar continuum filter, Losmandy GM-8 mount. Cannon 80D camera. 650 FL 12.5 mm eyepiece. I am proud of this dedicated solar telescope as I made it myself around a used Jaegers objective lens, bought on e-bay that had damaged coatings. A Moon Lite focuser, a Baader Planetarium Herschel Wedge. It has become my favorite telescope for sunspots!
