This home page provides access to full resolution magnetic field data obtained in the outer magnetosphere and in the solar wind by Prognoz-7.
The Prognoz 7 satellite was launched 30 October 1978 into an orbit with perigee 500 km and apogee 203000 km, orbital period was 98 hours
The data were obtained by an SG-70 fluxgate magnetometer provided by IZMIRAN's Space Magnetic Research Laboratory. The magnetometer had a range of +/- 60 nT and an accuracy of about 0.3 nT. It made one vector measurement every 10.24 sec.

Time span 1978/11/11 - 1979/05/30.

The ASCII format data set and the data description (originally generated at IZMIRAN/Russia) are placed at SPDF's FTP site FTP site
