When a CME hits the Earth, it lead to a geomagnetic storm, as the Earth's magnetosphere is disturbed by the incoming solar particles. The outcome, provided all the conditions are right, is the appearance of aurora in the night sky.
Coinciding with St. Patrick's Day, the sky turned green with the aurora put on a spectacular show last night, even at lower than usual latitudes, as a result of the severity of the storm. Aurora were visible in both the northern and southern hemisphere, from New Zealand, to the USA and throughout northern Europe.
You can learn more about the geomagnetic storm from the BGS website here: egu.eu/5461Z8

Thirty-two of the best Earth Observatory images will meet in Tournament Earth 3.0, but only one can be the winner. From March 2 through April 6, you can vote for your favorite images from the past year, whittling the total from 32 to 16 to 8 to 4 to 2 in a month-long tournament of remote sensing madness. The competition will be stiff in the four brackets — Data, Art, Event, and Photograph — so it is up to you to separate the winners from the losers. Come back each week to vote in each new round.
New Zealand is seldom photographed from orbit because it is one of the cloudier parts of planet, and because crew sleep periods often occur when the ISS passes over the area. Read more at http://earthobservatory.nasa.gov/IOTD/view.php?id=85332&src=googleplus
