5-Minute Averaged Solar Wind Magnetic Field Data


Availability: Archived at NSSDC, accessible from elsewhere

Time span: 1979-06-29 to 1983-12-31


This magnetic field data set is on ASCII magnetic tape created on a MODCOMP IV computer. The tape was made at NSSDC using the 1-min magnetic field averages from data set 78-079A-02D to calculate 5-min averages. The tape contains 18,488-byte physical records, each of which has one day's data in the form of a header record and 288 data records. The header record contains the year, day of year (Jan.1=1), and spacecraft position at start of the day in GSE coordinates. Each data record contains the 5-min averages of the magnetic field components in GSE coordinates and the field magnitude. Since the data are time continuous, intervals for which no data exist are indicated by having all the magnetic field components and the magnitude set to 0. Two time gaps do exist in the data set corresponding to ISEE 3 passes through the geomagnetic tail. These gaps are for days 209 to 304 of 1982 and day 356 of 1982 to day 304 of 1983.
