Summary

Description Contours of constant geomagnetic latitude and longitude (calculated using the 2000 epoch AACGM coordinate system based on the algorithm as described in Baker and Wing [A new magnetic coordinate system for conjugate studies at high latitudes, J. Geophys. Res., 94(A7), 9139–9143, 1989]). The latitude contours indicate 65, 70, and 75 degrees magnetic latitude, which corresponds roughly to the typical auroral oval. Also shown are contours of magnetic lonitude, separated by one hour of local time. This image was created by Eric Donovan. The image may be reproduced without permission, however it should be attributed to Eric Donovan of the University of Calgary.
