As seen to me through clear skies, this morning. the most active sunspots on the solar disk.
NOAA forecasters estimate a 55% chance of M-class flares and a 15% chance of X-flares on April 27th. The likely sources are sunspots 4420 and 4425, which have unstable 'delta-class' magnetic fields. Earth is in the strike zone for both active regions as reported by Spaceweather.com.
103mm Jagers refractor, Badder Planetarium safety prism, using neutral tensity 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 Jagers objective lens, bought on e-bay that had damaged coatings. A Moon Lite focuser, a Baader Planetarium Herschal Wedge. It has become my favorite telescope for sunspots!
