The expanding circular shadow is a wave of hot plasma and magnetism. Based on the time it took to reach the next sunspot, halfway around the sun, the tsunami was traveling faster than 110,000 mph.
Solar tsumanis always herald a CME, and this one was no exception. Soon after the tsunami broke, SOHO coronagraphs detected a plasma cloud leaving the sun:
NOAA analysts have modeled the CME’s trajectory and predict an Earth impact during the late hours of Aug. 29th, possibly sparking G1-class geomagnetic storms through midday on Aug. 30th.
