Abstract
An imaging photon detector (IPD) is routinely used with a Fabry-Perot interferometer (FPI) for observations of 630 nm air glow above Beverid ge (37.47 degrees S, 144.94 degrees E) 50 km north of Melbourne, Austr alia. A fourfold improvement in signal-to-noise ratio allowed air-glow observations to be continued during the present solar minimum when th e number of photons recorded by the detector often fell below 100 s(-1 ). The cooling system is described. Cooling curves and samples of data recorded during a period of low-intensity air glow are presented.
