SABER aurora - geomagnetic storm events

Three perspectives on the events that create geomagnetic storms: A storm from the Sun, a global perspective of an auroral event as seen from space and aurora as seen from Earth. Researchers at NASA's Langley Research Center are using the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) satellite to take new measurements of the E-region of the ionosphere - an active, charged layer that is crucial for the transmission of satellite, radio and GPS signals.
