The auroral photometer (AP) was a two-channel broad-band instrument that was used to determine the energy deposited in the upper atmosphere by energetic auroral electrons. The channels consisted of two Hamamatsu phototube detectors, a UV filter for each channel, and a field of view limiter for each channel. Both channels had circular fields of view, 11 degree full-cone. AP flew on the student-led SNOE mission.
