| HELIOPHYSICS PICTURE OF THE WEEK
"Planetary Fountain"
This image is an artist's conception of the Earth's "auroral plasma fountain," which sprays atmospheric ions out into space (within the Earth's magnetosphere) at a rate that varies from 50 to 1000 tons per day, depending on how active the aurorae are in response to solar wind conditions. In the image, the aurora appears as a greenish glow encircling the pole. The fountain is excited by the aurora at all local times, though it is steadier and more prolific in the sector toward the sun.
