At night in the absence of any other excitation mechanism the PL intensity should have a thermal amplitude level kTe, determined by the electron gas temperature Te. To the contrary Carlson found the nighttime PL over Arecibo was enhanced 3-10 times above thermal level intensities despite the absence of any known causative mechanism (e.g. Carlson et al, 1982). ...
