On September 18th Jeff Kretsch took a picture of the sun's corona using a Coronado PST and a handheld Lumix Camera at f1.7 1/500 second.  This was after SpaceWeather (https://spaceweather.com) issued an alert:

A CME HIT EARTH'S MAGNETIC FIELD TODAY:

"Minor G1-class geomagnetic storms are underway on Sept. 17th following the predicted arrival of a CME. The strike was, at first, seemingly weak and inconsequential. Now, however, Earth is passing through the CME's magnetized wake and experiencing geomagnetic disturbances. If storm conditions persist, auroras could become visible in northern-tier US states after nightfall."

The solar storms center around sunspot AR2871 (that was actually an old sunspot AR2860, returning after a two-233k trip around the far side of the sun. During its previous appearance in late August, the sunspot produced 1 M-class flare and 21 C-class flares. Since then, the sunspot's dark cores have diminished, but the surrounding storm system still has an air of menace.
