Giant sunspot AR2781. Images acquired with a 150 mm achromat, Quark H alpha filter and ASI174MM. Fair seeing. The Earth image was inset for size comparison.
A second image shows also the H-alpha view, but with the filter set a bit off-band. Lots of Ellerman bombs are detectable. This image was featured on the first page of SpaceWeather.com website.
About 50 minutes of evolution in just two seconds. Animation start at 10:52 U.T. Note the small flares that occur simultaneously (center and left):
