Paper Abstract

The data on spacecraft glow are discussed. The results of the observations of this phenomenon from the orbital stations confirming the contribution of solar and geomagnetic activity to the glow intensity are presented. The possible hypotheses about the mechanisms of this contribution are analyzed and the space weather parameters which affect the glow brightness are examined. The conclusion is made that there are two reasons that amplify the glow brightness: the increase of the upper atmosphere density on the low-Earth orbit (LEO) after a series of solar flares and global magnetic storms, and the increase of the intensity of solar extreme ultraviolet (EUV) radiation scattered in geocorona to the night side after isolate global magnetic storms. In the latter case the contribution of O++ ions to scattering should be taken into account, especially if subsequent large storm have the same type of commencement.
