Area of Science:

  • Space physics and heliophysics
  • Particle astrophysics
  • Planetary science

Background:

  • The Clementine spacecraft carried a charged-particle telescope (CPT) to measure energetic particles.
  • Energetic protons and electrons are crucial for understanding radiation effects and space weather.
  • Previous studies lacked comprehensive data on particle fluxes during specific space events.

Purpose of the Study:

  • To analyze energetic particle data collected by the CPT onboard Clementine.
  • To investigate solar energetic particle events and their impact on Earth's magnetosphere.
  • To compare CPT findings with data from other spacecraft missions.

Main Methods:

  • Utilized the charged-particle telescope (CPT) to measure proton and electron fluxes.
  • Analyzed data in specific energy ranges relevant to radiation effects and geophysical phenomena.
  • Observed particle behavior during solar energetic particle events and lunar occultation.
  • Compared CPT data with simultaneous measurements from GOES-7, SAMPEX, and GEOTAIL.

Main Results:

  • Measured energetic proton fluxes (10-80 MeV) from solar energetic particle events.
  • Observed energetic electrons (25-500 keV) of geophysical interest.
  • Detected particle wakes behind the moon in the magnetotail.
  • Recorded energetic electron bursts during magnetic storms and substorms.
  • Provided data on solar energetic protons and storm-time protons linked to an interplanetary shock on Feb. 21, 1994.

Conclusions:

  • CPT data offer valuable insights into energetic particle dynamics in space.
  • The instrument was effective in studying solar energetic particles and magnetospheric phenomena.
  • CPT data are particularly useful for multispacecraft studies of interplanetary disturbances and magnetospheric interactions.
