Our star continues to provide stunning sights as we approach solar maximum. This huge prominence, among the biggest I’ve ever seen, is visible in the hydrogen alpha wavelength, but it takes a specially designed scope or filter to see it. My 40mm Personal Solar Telescope (PST) is one such scope.
The prominence consists of superheated solar plasma suspended along magnetic field lines. It is not static, but changes constantly–sometimes the changes happen quickly and sometimes slowly. The appearance of this prominence had changed subtly by the end time of the sketch, so if you want to draw one of these monsters, be prepared to work fast!
