The Sun 8/6/2016

Solar activity is diminishing after a disappointing solar max. While white light images show just a couple of small sunspot groups (ARs 2571 and 2572), H-Alpha shows much more detail, including prominences, granularity, filaments and, in this case, minor flaring from AR 2571.  I've also added an inverted image from May, 2013, as a comparison.
