Spaceweather.com reports: That New sunspot 4513 poses a threat for strong M-class solar flares.
This new sunspot AR4513 is crackling with solar flares and its turning toward Earth. Yesterday's M8-class explosion produced an impressive CME just outside our planet's strike zone. NOAA forecasters estimate a 40% chance of more M-flares and a 10% chance of X-flares on Aug. 21. Seen to me through clear skies this morning.
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 Clave 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!
