The THEMIS All-Sky cameras, based here on Earth, take images and movies of the Northern Lights by looking up into the sky from horizon to horizon. The cameras take images and movies in black and white, gathering all the visible light from the aurora that they can. In this way, they can record even very faint aurora that our eyes cannot see.
These cameras are being placed in 20 locations, spread out across Canada and Alaska, where the Northern Lights are most likely to be seen. The images from the first All-Sky Camera deployed by THEMIS are shown below on this page. See the Canadian
THEMIS web page for more information about these cameras and their future locations.
The one All-Sky camera operating right now is in Athabasca, Canada. Here we see an aurora in the background of the house where the camera is located. On top of the house is a tiny dome, out of which the camera is peering and recording the aurora overhead. This movie was provided courtesy of the University of Calgary THEMIS team.
