Abstract:

IMP-8 (IMP-J) was launched by NASA on October 26, 1973 to measure the magnetic fields, plasmas, and energetic charged particles (e.g., cosmic rays) of the Earth's magnetotail and magnetosheath and of the near-Earth solar wind. IMP-8 continues to operate. The magnetic field experiment on the IMP-8 spacecraft utilizes a tri-axial fluxgate (saturable inductor) magnetometer. The instrument originally had three, automatically determined, ranges, +/- 12 nT, +/-36 nT, and +/- 108 nT, full scale. Because of a range-change circuit failure occurring in early July 1975, the experiment was commanded into a fixed +/-36 nT range on July 11, 1975 at 12:55:09 UT and has been in that range ever since. The measurements are A-to-D converted onboard, to an 8-bit resolution, yielding +/-0.14 nT quantization sensitivity, which is larger than the intrinsic sensor noise level of 0.025 nT RMS. Data consists of 15.36 sec magnetic field data, hourly magnetic field averages, and daily 1 minute magnetic field data. The parameters given are: spacecraft position in GSE and GSM coordinates; magnetic field vector, in GSE and GSM; the average magnetic field magnitude, and the variances of the magnetic field components. Other data include: - 1-Hour averaged magnetic field data for solar wind only - 1-Hour averaged magnetic field data for all orbit phases - 15.36 Sec Averaged Vector Magnetic Field Data Plots on Microfilm - 24-Hr Magnetic Field Summary Plots on Microfiche - 0.32 s GSE Magnetic Field Data - Hourly Averaged IMP Magnetic Field Data - 20-s CPME + EPE Particle, 15-s Magnetic Field and 1-min Plasma Merged Data Set - 5 Minute Field and Plasma Data from UCLA - 15 Sec Magnetic Field Plots on Microfilm For IMS Special Periods - 5-Min Averaged Interplanetary Field and Plasma, Select Parameters From 73-078A-0 - 5-Minute Averaged Interplanetary Magnetic Field and Plasma Data - 1-Minute Averaged Magnetic Vectors Data - 15-s Averaged Magnetic Vectors, CDF I8_H0_MAG, Version 2 - 15-s Averaged Magnetic Vectors, ASCII, Version 2 - 15 Second Averaged Magnetic Field Data, IEEE Binary, Version 2 Data are available from the NSSDC anonymous ftp site, OMNIWeb and CDAweb as well as from the PI web site: http://wind.nasa.gov/imp8/ See also: http://nssdc.gsfc.nasa.gov/database/MasterCatalog?sc=1973-078A&ex=1&ds=*
