Aurora are caused by the interaction of precipitating charged particles (electrons and ions) with the neutral gases of our atmosphere. Light from the Earth's aurora occur principally in two oval-shaped bands lying between ~65 and 75 degrees magnetic latitude and centered on the northern (aurora borealis) and southern (aurora australis) magnetic poles. IMAGE observes the aurora in several important wavelengths and has captured its first geomagnetic substorm. These observations are caused by precipitating electrons. A selected frame from this sequence is available as a TIFF or JPEG image.
