SOLAR TSUNAMI AND CME: An explosion on the sun during
the early hours of July 21st created a solar tsunami wave and hurled a
CME toward Earth. The CME's arrival on July 23rd could spark minor to
moderate geomagnetic storms with auroras at high latitudes. Full story @
Soon after the explosion, the US Air Force reported a Type II solar radio burst--a natural form of radio noise produced by shock waves in the leading edge of a CME. Characteristics of the burst suggested that a CME was tearing through the sun's atmosphere at a speed of 1063 km/s (2.4 million mph).
Coronagraphs onboard the Solar and Heliospheric Observatory (SOHO) have since seen the CME:
In the movie we see a superposition of multiple CMEs. The brightest clouds at the 8 o'clock and 10 o'clock positions may be from farside eruptions. They are not heading for Earth. Of greater interest is a faint full-halo CME which emerges just before 0206 UT. That one was launched by the tsunami and is squarely inside the Earth strike zone. NOAA forecasters expect it to arrive on July 23rd, possibly sparking G2-class geomagnetic storms.
