-------------------------------------------------------------------- readme for Prognoz-6 This directory contains magnetic field data obtained in the outer magnetosphere and in the solar wind by Prognoz 6 between 1977/09/26 and 1978/01/22. The Prognoz 6 satellite was launched 22 September 1977 into an orbit with apogee of 200,000 km, perigee of 500 km, and an orbital period of 95 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 Magnetic and position data format: Word Format Description 1 I3 Year 2 I3 Month 3 I3 Day 4 I3 Hour 5 I3 Minute 6 I3 Second 7 F7.2 Btotal [nT] 8 F7.2 Bx [nT], GSE 9 F7.2 By [nT], GSE 10 F7.2 Bz [nT], GSE 11 F7.2 By [nT], GSM 12 F7.2 Bz [nT], GSM 13 F8.2 X [Re], satellite position, GSE 14 F8.2 Y [Re], satellite position, GSE 15 F8.2 Z [Re], satellite position, GSE 16 F8.2 Y [Re], satellite position, GSM 17 F8.2 Z [Re], satellite position, GSM -------------------------------------------------- Note that an FTPHelper interface to this dataset, providing data subsetting and and graphical browsing, is available at "http://ftpbrowser.gsfc.nasa.gov/" IZMIRAN contact persons V.
