GEOMAGNETIC STORM WATCH (G1-CLASS): A CME is heading for Earth. Minor G1-class storms are possible when the storm cloud arrives on March 27-28. Coronagraphs onboard the Solar and Heliospheric Observatory (SOHO) made this movie as the CME left the sun on March 25th:
The CME is faint, but it is moving fast (959 km/s) squarely inside the Earth strike zone. It could deliver a sharp blow to our planet’s magnetic field despite its low luminosity in the coronagraph movie.
NASA analysts have modeled the CME’s trajectory. Note the yellow dot in the animation below. That’s Earth.
