|prominence (prŏm'ə-nəns) Pronunciation Key
An eruption of tonguelike clouds of glowing ionized gas extending from the Sun's chromosphere and sometimes reaching hundreds of thousands of kilometers into space. When viewed against the solar surface instead of along the edges of its disk, prominences appear as dark, sinuous lines known as filaments. Usually associated with sunspot activity, solar prominences can influence Earth's atmosphere by interfering with electromagnetic activity. ◇ Active prominences erupt suddenly and usually disappear within minutes or hours. Quiescent prominences form more smoothly and can last for several months. See also solar flare.
