24-Sec Electron Parameters (N,V,T,H) Giacobini-Zinner Comet Encounter


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1985-09-10 to 1985-09-14


This data set contains electron measurements at a time resolution of 24 seconds made during the comet Giacobini-Zinner encounter by ICE in September 1985. The data are identical in form to those included in data set 78-079A-01N, but this data set includes two additional days of data and only the comet encounter data are contained here. Each data record in these files contains the date and time, the core density, the maximum and minimum core temperatures, the halo density, the maximum and minimum halo temperatures, the total electron density, the bulk flow speed, the bulk flow azimuth, the maximum and minimum total temperatures, the electron heat flux (erg/cm**2-sec), and the electron heat flux azimuth (degrees; 0 and 360 degrees correspond to heat flux directed anti-sunward, 90 degrees corresponds to heat flux directed toward dawn). Since the core and halo parameters are derived from a straight numerical integration over the entire electron distribution, the total density does not necessarily equal the sum of the core and halo densities. Spacecraft trajectory information for the comet encounter, provided by JPL, are archived separately as data set 78-079A-00E. Magnetic field data at 0.33-second time resolution for the comet encounter are in data set 78-079A-02N.
