Bulk plasma properties at geosynchronous orbit
[1] We present a comprehensive study of plasma properties at geosynchronous orbit for electron and ion energies between 1 eV and 45 keV, between 1990 and 2001. The variations of temperature and density are analyzed as functions of local time, magnetospheric convection strength, and the strength of the ring current. Various parameters derived from temperature and density are calculated to elucid...
متن کاملAn initial response of magnetic ®elds at geosynchronous orbit to Pi 2 onset as observed from the dip-equator
Fluxgate magnetometer data recorded at the dip-equator (Huancayo, Peru; 1.44°N, 355.9° in geomagnetic coordinates; 12.1°S, 75.2°W in geographic coordinates; L = 1.00) with higher accuracy of timing (0.1 s) and amplitude resolution (0.01 nT) were utilized to survey an onset of Pi 2 pulsations in the midnight sector (2100±0100 LT) during PROMIS (Polar Region and Outer Magnetosphere International ...
متن کاملSpacecraft surface charging within geosynchronous orbit observed by the Van Allen Probes
Using the Helium Oxygen Proton Electron (HOPE) and Electric Field and Waves (EFW) instruments from the Van Allen Probes, we explored the relationship between electron energy fluxes in the eV and keV ranges and spacecraft surface charging. We present statistical results on spacecraft charging within geosynchronous orbit by L and MLT. An algorithm to extract the H+ charging line in the HOPE instr...
متن کاملStatistical analysis of relativistic electron energies for cyclotron resonance with EMIC waves observed on CRRES
[1] Electromagnetic ion cyclotron (EMIC) waves which propagate at frequencies below the proton gyrofrequency can undergo cyclotron resonant interactions with relativistic electrons in the outer radiation belt and cause pitch-angle scattering and electron loss to the atmosphere. Typical storm-time wave amplitudes of 1–10 nT cause strong diffusion scattering which may lead to significant relativi...
متن کاملProbing the relationship between electromagnetic ion cyclotron waves and plasmaspheric plumes near geosynchronous orbit
[1] Plasmaspheric plumes created during disturbed geomagnetic conditions have been suggested as a major cause of increased occurrences of electromagnetic ion cyclotron (EMIC) waves at these times. We have catalogued occurrences of strong Pc1 EMIC waves from 1996 through 2003 at three automated geophysical observatories operated by the British Antarctic Survey at auroral zone latitudes in Antarc...
