            "title": "Why Auroras Erupt",
            "description": "Why does the aurora borealis—the typically steady green bands of light common in the nighttime sky over the Arctic—occasionally erupt in bouts of activity that leave the sky shimmering with a full palette of reds, whites and purples? Scientists have long known that disturbances in Earth's magnetic field driven by the solar wind can trigger such auroral eruptions, but it hasn't been clear whether the disturbances originate near the Earth or at more distant points closer to the moon. In recent years, a series of five satellites and a network of ground-based instruments in the Arctic have finally helped provide an answer. Hermetically-sealed cameras, called All Sky Imagers, placed strategically throughout the American and Canadian Arctic, look upward to observe nearly the entire arc of the sky where auroras occur. The ground network, considered the sixth \"satellite\" of NASA's aurora-monitoring THEMIS mission, takes auroral snapshots each three-seconds all night long, every night. In 2008, it helped make a breakthrough discovery: the magnetic disturbances that cause auroras to erupt begin about a third of the way to the moon when stressed magnetic lines reconnect and send massive bursts of energy toward Earth. The visualization below shows the first major aurora eruption that the imagers observed. || ",

            "description": "A collection of ground-based All-Sky Imagers (ASI) makes an important component of the THEMIS mission in understanding the interaction of the magnetosphere and aurora. It is sometimes referred to as the sixth THEMIS satellite. Descriptions of the instruments are available on the THEMIS-Canada Home Page. Imagery from each camera is co-registered to the surface of the Earth and assembled into a view of the auroral events. This movie presents data from the first large auroral substorm since the THEMIS launch. The substorm reached its maximum between 6:00 and 7:00 UT. Note that the ASI data in this movie are assembled from significantly higher resolution datesets than the earlier version, THEMIS/ASI Nights. The higher resolution enables you to see much finer details in the aurora structure. In addition, one notices trees circling the horizon visible to the cameras located in western Canada. || ",

            "description": "This movie is an auroral substorm event observed by the visible light camera aboard the Polar spacecraft. Because the visible light camera records in a single broad range of wavelengths, we do not have color imagery of the event. For this movie we will color the aurora green since that is the dominant color in most cases. The VIS camera is also low resolution so the fine aurora details visible from the ground are not apparent in this movie. || ",

            "description": "The IMAGE spacecraft observed intense auroral displays in the Fall of 2003 as the material from the coronal mass ejection swept past the Earth.  The pressure against the Earth's magnetosphere caused it to dump more electrons into the upper atmosphere, creating auroral displays, as we see here over the South Pole.  This is a view of the IMAGE data reprojected onto a model of the Earth. || ",

The protons for this aurora came from the incoming solar wind. They made it though the Earth's magnetic shield in a magnetic reconnection event higher in the magnetosphere which was detected by the Cluster satellite. Note: A 'corner' appears in the data in the beginning as the IMAGE spacecraft moves into a position where it can view the entire north polar region. || ",
