Active Aurora Associated with the Geomagnetic Storm of June 8, 2000

The Wideband Imaging Camera (WIC), one of the three instruments in the IMAGE Far Ultraviolet (FUV) Imaging System, captured an active aurora that occurred during the geomagnetic storm of June 8. The storm, which was relatively moderate (80 gamma), was triggered by a coronal mass ejection (CME) that was observed at the Sun on June 6. The CME was associated with two X-class flares.

The auroral emissions observed with the FUV/WIC are from molecular nitrogen that is excited by precipitating electrons. WIC images acquired between 15:40 UT and 19:25 UT on June 8 have been assembled into an MPEG movie, which shows clearly the dynamic nature and fine structure of the aurora.
