OGO 6 Bennett Ion Mass Spectrometer Data

This home page provides access to data from the OGO 6 BIMS experiment for the time period from June 12, 1969 to December 31, 1970 in ASCII format.The instrument measures the ion densities of seven ion species (H+, He+, N+, O+, N2+, NO+, O2+). Each data record lists the density and orbit parameters for one specific density measurement. The ASCII data set also contains needed spacecraft position data, IGRF model parameters, and indices.

Time Resolution: ~40 seconds
