                         aareadme for Prognoz-7


This directory contains magnetic field data obtained in the outer 
magnetosphere and in the solar wind by Prognoz 7 between 1978/11/11 
and 1979/05/30.

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.

Data files contain ASCII records with time information and magnetic field 
and spacecraft position data in both GSE and GSM coordinate systems.  Each 
file has data for one day on day boundaries.  A table of start/stop times 
of continuous data is provided as prognoz6.tab.  The files are named 
pYYMMDD.pr6, showing year month, and day of data
