The ground-based all-sky imager (ASI) was an essential instrument component of the storm mission to study the flow of solar wind energy through the magnetosphere

ASI plays two key roles in identification of the times locations and modes when energy is released and quantification of energy loss to atmosphere. The ASI array consisting of observatories spanning from alaska to canada offers an unprecedented opportunity to monitor the nightside responses due to the interactions of solar wind and magnetosphere. The implementation of this imaging array can capture the magnetospheric rapid evolution of fine-scale structure of green-line (557.7 NM) and red-line (630.0 NM) emissions in a wide area of the nightside auroral oval where the most of substorms occur. The ASI array provides the precise timing and location of the auroral activation relative to explosive magnetotail activity. The objectives of this proposal will investigate (1) to determine the methodology to estimate the precipitating electron energy and energy flux using ASI images from different emissions and (2) determine the methodology to automatically identify substorms magnetospheric modes auroral features such as streamers auroral arcs substorms etc. And auroral oval boundaries. We will use the data from APL S ground-based multispectral imaging array stationed in alaska for analysis and demonstration in this research.
