A collection of ground-based All-Sky Imagers (ASI) make up another important component of the THEMIS mission. 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 the lower resolution quick-look data sets. These create some extra pixellation of the data in the static high-resolution views. This animation has been superceded by ID 3590: THEMIS/ASI Nights-High Resolution, which uses higher-resolution ASI data.
