All-Sky Imager (ASI)

The ground-based All-Sky Imager (ASI) array is an important component of the STORM mission to complement global magnetospheric imaging from space. The ASI array, consisting of 14 observatories spanning Alaska and Canada, offers an unprecedented opportunity to monitor the rapid evolution of fine-scale structure in a wide area of the nightside auroral oval. The ASI array provides the precise timing and location of the auroral activation relative to explosive magnetotail activity.
