Auroral and Airglow Photometer

NSSDCA ID: 1961-015B-04

Mission Name: Injun 1
Principal Investigator:Dr. Brian J. O'Brien


A photometer was included in the payload of Injun 1 for the purpose of measuring the auroral and airglow intensities of the atomic oxygen green line at 5577 A. A malfunction prevented the separation of Injun 1 from the Naval Research Laboratory satellite, GREB 3 (also known as Solrad 3). Greb 3 completely filled the field of view of the Injun 1 photometer. Consequently, no useful auroral or airglow data were obtained, and the experiment was a failure. The instrument did operate for the lifetime of the satellite, about 18 months.
