A Moreton wave is a kind of shock wave on the Sun's chromosphere. Described as a kind of solar "tsunami", they are generated by solar flares. They are named for American astronomer Gail Moreton, who first reported their existence.

Moreton waves propagate at a speed of 500-1500 km/s, and occur where a coronal MHD fast-mode weak shock wave intersects the chromosphere. Moreton waves can be observed primarily in the band.[1]
