Several potential observational possibilities are explored at greater length, particularly in the ultraviolet. A description of Aurora 1 with emphasis on the ultraviolet and quadrant photometers is given. The system including the complete satellite and its orbit is considered with respect to acquiring photometer and combined photometerparticle measurements. Quantum efficiency variation in the ultraviolet photometer at long wavelengths is presented and interpreted as arising from color center formation in the photocathode. Photometer calibration is treated in considerable detail starting from basic definitions and derivation of important formulas. Finally there are appendices on the status of ultraviolet interference filters and sodium salicylate for ultraviolet calibration.233 ppengCopyright is held by the author, unless otherwise indicated.
