Submission + - Telescope Spots Solar Tsunami

scdeimos writes: The prototype of a new solar patrol telescope in New Mexico recorded a tsunami-like shock wave rolling across the visible face of the Sun following a major flare event on Wednesday, Dec. 6. The shock wave, known as a Moreton wave, also destroyed or compressed two filaments of cool gas at opposite sides of the solar hemisphere.

"These large scale 'blast' waves occur infrequently, however, are very powerful. They quickly propagate in a matter of minutes covering the whole Sun, sweeping away filamentary material," said Dr. K. S. Balasubramaniam. "It is unusual to see such powerful waves encompassing the whole sun from ground based observatories. Its significance comes from the fact that these waves are occurring near solar minimum, when intense activity is yet to pick up." has a nice 480x360 GIF animation showing the wave spreading across the surface of the sun.

Consider the postage stamp: its usefulness consists in the ability to stick to one thing till it gets there. -- Josh Billings
