Abstract. We show a case of an outer zone magnetospheric electromagnetic wave propagating at the Gendrin angle, within uncertainty of the measurements. The chorus event occurred in a "minimum B pocket". For the illustrated example, the measured angle of wave propagation relative to the ambient magnetic field θ kB was 58 • ± 4 • . For this event the theoretical Gendrin angle was 62 • . Cold plasma model is used to demonstrate that Gendrin mode waves are right-hand circularly polarized, in excellent agreement with the observations.

“…The fully operational complement of Geotail plasma, magnetic field, and plasma wave instruments, designed to investigate magnetospheric plasmas, were used in the plasma regime identification process used for this study (see Frank et al [ 1994], Kokubun et al [ 1994], Matsumoto et al [1994], and Mukai et al [1994] for relevant instrument descriptions). We briefly outline the identification process which is detailed in Paper 1.…”

Abstract. We investigate the spatial distribution, solar-terrestrial correlation, and basic statistics of a long sequence of plasma regime identifications through the probability of observation P at downtail distances of-30 < Xagsm < 210 RE, in an aberrated GSM coordinate system. The data are from Geotail spacecraft measurements obtained from October 1992 through October 1994. Earth's local plasma environment has been classified into five principal plasma regimes: PS, the plasma sheet, LB, the lobe (vacuum lobe, with only trace plasma content), and BL, the magnetospheric boundary layer, which together comprise the magnetosphere proper, and MS, the magnetosheath, and SW, the nearby solar wind.

ASPI experiment: measurements of fields and waves on board the INTERBALL-1 spacecraft

Abstract. The plasma-wave experiment ASPI (analysis of spectra of plasma waves and instabilities) on board the INTERBALL spacecraft is a combined wave diagnostics experiment. It performs measurements of the DC and AC magnetic ®eld vector by¯ux-gate and searchcoil sensors, the DC and AC electric ®eld vector by Langmuir double probes and the plasma current by Langmuir split probe. Preliminary data analysis shows the low noise levels of the sensors and the compatibility of new data with the results of previous missions. During several months of in-orbit operation a rich collection of data was acquired, examples of which at the magnetopause and plasma sheet are presented in second part of the paper. Scienti®c objectivesThe INTERBALL project is orientated towards the investigation of the interaction between di erent parts of the magnetosphere in relation to changes in the solar wind and ionosphere. First INTERBALL-1 orbits passed through the solar wind, bow shock, magnetosheath and magnetopause regions. Several months later the orbit apogee shifted to the near-Earth magnetotail, so that INTERBALL-1 observed the tail lobes and the plasma sheet. These orbit parameters allow the neutral sheet region to be studied for several hours.Plasma waves and¯uctuations play a crucial role in the highly collisionless space plasma. Waves and¯uctu-ations are of particular importance at the plasma boundaries such as bow shock, magnetopause, neutral sheet, and plasma sheet boundary layer. Wave-particle, interactions in the plasma result in processes like: (1) anomalous transport (pitch-angle and spatial di usion, conductivity, viscosity); (2) energy redistribution and plasma heating; (3) generation of anisotropic distribution functions and their relaxation; (4) triggering of large-scale instabilities.The speci®c objectives of the ASPI wave and ®eld experiment on board INTERBALL-1 are:1. The study of the¯uctuation characteristics in di erent regions of the magnetosphere and the use of these data as high-time-resolution indicators of plasma phenomena. 2. The determination of the micro-scale plasma characteristics (e.g. di usion and anomalous transport coe cients, wave-wave and wave-particle coupling).
