I got a nice view of our star through todays hazy skies at a range of wavelengths: Starting on the left and looking at ultra violet wavelengths the bright white areas indicate where the magnetic fields are at there strongest. The middle shot is at visible wavelengths showing sunspots. The image on the right is at near infra red wavelengths and shows what our star looks like in hydrogen light - the dark lines are clouds of cool plasma floating above the solar surface, with the bright patches being areas of high temperature plasma and flaring, all shaped by magnetic field lines.
