Magnetic Conjunctions of ISEE 1 with ESA- GEOS 2 and STP P78-2, on Microfilm


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

Time span: 1979-03-15 to 1981-02-17


This data set consists of microfilmed listings of magnetic conjunctions computed at NSSDC. The target satellite is ISEE 1, and the orbits of ESA-GEOS 2 and STP P78-2 were examined to determine magnetic conjunctions, i.e., times when those satellites were located on (or within a specified distance of) the same magnetic field line that passed through the target satellite. In addition to the time period, the listing provides spacecraft locations, separation distance, distance to the surface of the earth along the field line, and identification of the magnetic field model used. This data set is identified under three different IDs, one for each of the three spacecraft involved (77-102A-00F, 78-071A-00D, and 79-007A-00D).
