sunspot : a dark area if the photosphere of the sun that is cooler then the surrounding areas and that has a strong magnetic field
prominence : a loop of relatively cool, incandescent gas that eestends above the photosphere
solar flare : a brief eruption of intense high-energy radiation from the sun's surface, associated with sunspots and causing electromagnetic disturbances on the earth, as with radio frequency communications and power line transmissions.
coronal mass ejectionis : a giant cloud of solar plasma drenched with magnetic field lines that are blown away from the Sun during strong, long-duration solar flares and filament eruptions.
aurora : a natural electrical phenomenon characterized by the appearance of streamers of reddish or greenish light in the sky, usually near the northern or southern magnetic pole.
