Auroras are the most visible manifestation of the Sun's effect on Earth. They are seen as colorful displays in the night sky, known as the Northern or Southern Lights. They are caused by the solar wind, a stream of plasma -- electrically charged atomic particles -- carrying its own magnetic field, interacting with the earth's magnetic field. Normally, the main region for this impressive display is the 'auroral oval', which lies at around 65-70 degrees north or south of the equator, encircling the polar caps. However, auroras can occur at even higher latitudes. One type is known as a 'theta aurora' because seen from above it looks like the Greek letter theta -- an oval with a line crossing through the center.

Scientists wanted to know why. Now, researchers have provided a clear answer.

The image represents light in the 131 Angstrom wavelength, which is particularly good for seeing flares, and which is typically colorized in teal.

In this case that energy came from a coronal mass ejection (CME) associated with a July 12 X-class flare.

Early in the morning of July 5, 2012, there was an M6.1 flare. It peaked at 7:44 AM EDT. This caused a moderate -- classified as R2 on the National Oceanic and Atmospheric Administration's space weather scale -- radio blackout that has since subsided.

The region fired off two M-class flares and two coronal mass ejections (CMEs) on June 13 and June 14, 2012. Thu, 14 Jun 2012 19:37:55 EDT //www.koonmotors.com/releases/2012/06/120614193755.htm
