Or movies.
Spaceweather.com has it as a movie and adds an explanation:
The shadowy wave emerging from the blast site is a “solar tsunami“–a swell of hot magnetized plasma about 100,000 km tall racing along the sun’s surface at 250 km/s (560,000 mph).
Strange but true: You can “hear” a solar tsunami. When such a shock wave ripples through the sun’s atmosphere, it causes solar plasma to oscillate, generating natural radio emissions detectable by shortwave receivers on Earth.
That spot above is probably larger than Earth. Sort of puts you in your place.
