High Time Resolution Electric Field Events (Selected Special Periods)


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

Time span: 1973-12-18 to 1974-10-20


This data set, on 16-mm film, contains listings as well as accompanying plots. The data on the plots could not be identified, and the plots should be ignored. The listings were obtained whenever the ELF noise level in channel 11 exceeded 1.0 telemetry unit, and, with caution, could be presumed to be the times of bow-shock crossings, as labeled. The listings provide the average values of the noise, in mV/m, from channel 11, through the spacecraft's orthogonal X and Y antennas. The X antenna was improperly deployed, and the values under the X column should be ignored. The values (mV/m) under the Y column are the averages during successive 0.64 s, i.e., approximately during a quarter of a spin period. The column labeled "sector" provides the angle of the X antenna, measured from the GSE X axis. This tabulation is followed by another tabulation, labeled "PG SQ PEAK," which provides the averages (designated by a "0" in the line, under "MD") as well as the peak values (designated by a "1") of the rms noise (mV/m) in each of the 11 channels, spanning a total range of 0.01-3200 Hz. Each line of data was obtained during a time interval of 8 x 1.278 s, i.e., approximately four spin periods. Occasionally, there are negative numbers in the columns; they should be rejected.
