TLDR
In this article, the authors examined statistical data on optical and radio-auroral phenomena to establish the latitude-versus-time pattern for the causal particle precipitation and found that two distinct particle populations are involved on the average.About:

Postmidnight chorus: A substorm phenomenon
TL;DR: In this paper, the post-midnight chorus was detected in the midnight sector of the magnetosphere in conjunction with magnetospheric substorms and the characteristics of these emissions such as their frequency time structure, emission frequency with respect to the local equatorial electron gyrofrequency, intensity-time variation, and the average intensity were investigated.
Journal ArticleDOI
Global morphology of ionospheric scintillations
TL;DR: In this article, a review of the available amplitude and phase scintillation data is presented, where the effect of magnetic activity, solar sunspot cycle, and time of day is shown for each three latitudinal sectors.
Journal ArticleDOI
Two types of magnetospheric ELF chorus and their substorm dependences
TL;DR: In this paper, the distribution of extremely low frequency (10-1500 Hz) magnetospheric chorus to all local times and latitudes is investigated in order to determine dependence on substorms, and to evaluate the conditions under which chorus is generated.
Journal ArticleDOI
Bulk motion of the magnetosphere
TL;DR: In this article, an upper atmosphere geophysical measurements are surveyed to determine to what extent the available data support the concept of bulk motion of the magnetosphere (convection) and the associated electric field.

Magnetospheric chorus - Occurrence patterns and normalized frequency
W. J. Burtis,R. A. Helliwell +1 more
TL;DR: In this paper, the authors analyzed 400 hours of continuous broadband data obtained by the OGO 3 satellite to provide a statistically accurate description of band-limited (magnetospheric) chorus and concluded that most magnetospheric chorus consists of rising emissions which are probably generated by gyroresonant electrons slightly off the equator.

Limit on stably trapped particle fluxes
Charles F. Kennel,H. E. Petschek +1 more
TL;DR: The limit on stably trapped particle fluxes determined theoretically and compared with data from Explorer satellites was first established in this paper, and the limit was later confirmed by the International Journal of Astronautics.

Direct Measurement of Particles Producing Visible Auroras
TL;DR: In this paper, the nature of particles producing two visible auroras at Fort Churchill, Canada, was determined with the aid of rocket-borne detectors, and it was found that a major fraction of the auroral light was produced by electron with energies of less than 10 kev.
Journal ArticleDOI
Tail of the magnetosphere
TL;DR: Tangential stress effects on magnetosphere tail with regard to magnetic field intensity and direction, trapped particle fluxes and low energy cosmic ray cut-off were studied in this article, where the authors considered the effect of magnetic field and particle flux on the magnetosphere.
