"The tsunami-like shock wave, formally called a Moreton wave, rolled across the hot surface, destroying two visible filaments of cool gas on opposite sides of the visible face of the Sun.
Astronomers using a prototype of a new solar telescope in New Mexico recorded the action.
"These large scale 'blast' waves occur infrequently, however, are very powerful," said K. S. Balasubramaniam of the National Solar Observatory (NSO) in Sunspot, NM, "They quickly propagate in a matter of minutes covering the whole Sun, sweeping away filamentary material."
It is unusual to see such an event from a ground-based observatory, Balasubramaniam said. And it was also unusual that it occurred near solar minimum, when the Sun is at its least active during an 11-year cycle."
