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 MIT Faraday cup experiment on IMP 8 measures currents from solar
wind ions, and from these measurements the velocity, density, and
... temperature of the solar wind are calculated. Fine resolution, hourly
average, and daily average data can be obtained via anonymous ftp from
MIT (ftp://space.mit.edu/pub/plasma/imp/www/imp.html).
IMP-8 solar plasma Faraday cup magnetic field data can be obtained
from NSSDC. Other data from this experiment at NSSDC include:
- Plasma Parameter Data from IMP-8, Faraday Cup Instrument
