Keogram for Fort Simson, NWT, Canada. The vertical axis shows magnetic latitude along a magnetic northâsouth meridian of an image focused by a fish eye lens on a 256 by 256 sensor array. The horizontal axis is universal time and the color scale shows the intensity of light at different zenith angles. Vertical dashed lines are times of the onset of fast flows at THEMIS spacecraft.
