in Tucson and colleagues used ground-based detectors to monitor changes in the solar surface due to the reverberation of sound waves inside the sun.

Washington, Aug 19 (ANI): Scientists at Southwest Research Institute and the National Solar Observatory
have developed the first detailed images of solar wind structures as plasma and other particles from a coronal mass ejection (CME) travelled 93 million miles and impacted Earth, thanks to NASA's STEREO spacecraft.
It is possible that the current sunspot cycle, cycle 24, was seeded with magnetic fields from cycle 23, or even an earlier cycle, cycle 22," says Matt Penn of the National Solar Observatory

The fact that there are three separate lines of evidence all pointing in the same direction is very compelling," the Telegraph quoted Frank Hill, of the National Solar Observatory
in New Mexico, who worked on one of the studies, as saying.
