Abstract

An observational program was designed to enhance the knowledge of the behavior of the proton auroral oval at mid-latitudes as a function of local time and global auroral activity for the purpose of determining the proton energy input rates into the atmosphere. Ground-based observations of H_(beta ) 4861 angstrom and N₂⁺ 4709 angstrom auroral emissions were made from Ottawa, Canada (45.2 degree(s) North, 283.7 degree(s) East) during most new moon periods from October 1977 to May 1981. Data were collected with a filter wheel photometer operated in the meridian scanning mode at a rate of about two scans per minute. Corrections for instrumental sensitivity and for atmospheric extinction and viewing angle were applied to the raw data. A subset of the final results was used in the current analysis to investigate the relationship between the brightness of the most intense mid-latitude proton aurora and auroral magnetic activity.
