This paper presents NO measurements in the thermosphere, made by the halogen occultation experiment (HALOE) on the upper atmosphere research satellite. The authors found a large enhancement in NO mixing ratios in conjunction with a large geomagnetic storm, particularly for altitudes greater than 100 km. The enhanced NO densities appeared to decay away with decay times on the order of one or two days. When looked at globally, there was a strong correlation of NO increases versus latitude and altitude, with auroral regions, with the effects being much smaller in low latitude regions.
