The CME was propelled toward Earth on May 17th by an M3-class solar flare in the magnetic canopy of sunspot AR1748. SOHO took this picture of the CME racing away from the sun at 1500 km/s (3.4 million mph):

A CME hit Earth's magnetic field on May 18th at around 0100 UT. Although it was just a glancing blow, the impact was enough to spark a G1-class geomagnetic storm. In the United States, Northern Lights descended as far south as Pawnee Buttes, Colorado:

MINOR STORM: A minor (Kp=5) geomagnetic storm is in progress following the glancing impact of a CME during the early hours (~0100 UT) of May 18th. High latitude sky watchers should be alert for auroras.
INCOMING CME:. Although this is not the strongest flare we've seen from AR1748, it could be the most geoeffective. The explosion hurled a CME into space that is expected to hit Earth's magnetic field on May 19th. NOAA forecasters estimate a 75% chance of polar geomagnetic storms when the cloud arrives.
The Solar and Heliospheric Observatory took this picture of the CME leaving the sun at 1500 km/s (3.4 million mph) on May 17th:
In the video, the CME appears to hit Mercury, but it does not. It is merely passing in front of the first planet. Instead the CME will deliver a glancing blow to Earth's magnetic field on May 19th. Aurora alerts:
