Giant sunspot 4478

Seen to me through clearing skies and as reported by Spaceweather.com Giant sunspot 4478 has been quiet for days. But now that the sunspot has rotated fully onto the solar disk, we can see that it has a mixed-polarity (delta-class) magnetic field that harbors energy for X-class explosions. A major flare could be in the offing.

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!
