Fluxgate Magnetometer Jovian Encounter 5 minute Averages


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1974-12-02 to 1974-12-03


This data set consists of one BCD magnetic tape created at NSSDC from a card deck supplied by the experimenter. The data consist of 5-min averaged magnetic field values obtained during the 12-h interval centered on the closest approach of Pioneer 11 to Jupiter. During this period, the spacecraft was within 8 Jovian radii of the planet. The data are time-continuous, except for a 1-h gap at perijove due mainly to spacecraft occultation. Each 5-min record contains spacecraft position information (Zenocentric distance, latitude, and system I and system III longitudes), field Cartesian components in celestial inertial coordinates, field spherical polar components in a Zenocentric coordinate system, and the number of finer time scale points in the 5-min average. See Mead, J. Geophys. Res., v. 79, p. 3514, for a discussion of the relevant coordinate systems. See Acuna and Ness, J. Geophys. Res., v. 81, p. 2917, for a discussion of the model planetary field derived from these data. There were several comment cards supplied with the card deck, and these have also been put on the magnetic tape.
