New camera provides tantalizing clues of new atmospheric phenomenon
WASHINGTON, Nov. 29, 2012—Hoping to expand our understanding of auroras and other fleeting atmospheric events, a team of space-weather researchers designed and built NORUSCA II, a new camera with unprecedented capabilities that can simultaneously image multiple spectral bands, in essence different wavelengths or colors, of light. The camera was tested at the Kjell Henriksen Observatory (KHO) in Svalbard, Norway, where it produced the first-ever hyperspectral images of auroras—commonly referred to as “the Northern (or Southern) Lights”—and may already have revealed a previously unknown atmospheric phenomenon.
