ΚΠ
1986 New Scientist 31 Jan. 21/2 Scientists checking UV emissions have dubbed the phenomenon ‘electroglow’, but are at a loss to explain the mechanism behind it.
1986 A. L. Broadfoot et al. in Science 4 July 75/3 The emission is more or less uniformly distributed over the sunlit hemisphere [of Uranus]... These emissions are distinct from dayglow and aurora, and we suggest the name ‘electroglow’ for them.
2004 Planetary & Space Sci. 52 1436/1 Another source of ‘optical noise’ comes from the emissions that can be excited by particle precipitations in planetary atmospheres (aurora, day-glow, electroglow).
