A study of quasi-periodic ELF-VLF emissions at three Antarctic stations: evidence for off-equatorial generation?

Autor: K. Morrison, M. J. Engebretson, J. R. Beck, J. E. Johnson, R. L. Arnoldy, L. J. Cahill ,Jr, D. L. Carpenter, M. Gallani

Publikováno v: Annales Geophysicae, Vol 12, Pp 139-146 (1994)

The spatial extent and temporal behaviour of quasi-periodic (QP) intensity modulations of 0.5-2 kHz ELF-VLF signals were investigated in a comparative study of data collected at the Antarctic stations of South Pole (L=14), Halley (L=4), and Siple

Magnetopause crossings observed at 6.6RE

Autor: J. R. Winckler, L. J. Cahill

Publikováno v: Journal of Geophysical Research: Space Physics. 104:12229-12237

Thirty-five boundary crossing events, many with multiple crossings, have been observed in data from the GOES 6 and 7 geostationary satellites in the years 1989, 1990 and 1991. Many of the crossings within these events appear to have been caused prima

Periodic magnetopause oscillations observed with the GOES satellites on March 24, 1991

Autor: L. J. Cahill, J. R. Winckler

Publikováno v: Journal of Geophysical Research. 97:8239

The GOES 6 and 7 satellites were in the dayside magnetosphere late on March 24, 1991, when the magnetopause moved in to geosynchronous orbit. Observations on GOES 6 near 1030 local time (LT) indicated six inward and outward periodic movements of the

The magnetopause at 5.2REon August 4, 1972: Magnetopause shape and structure

Autor: L. J. Cahill, R. L. Kaufmann

Publikováno v: Journal of Geophysical Research. 82:1573-1584

The relatively large magnitude magnetopause field observed in several crossings associated with the ATS 5 and Explorer 45 satellites on August 4, 1972, is used to examine the structure of the magnetopause. The discussion covers magnetopause normals a

Auroral radar and rocket double-probe observations of the electric field across the Harang discontinuity

Autor: R. A. Greenwald, Erling Nielsen, L. J. Cahill

Publikováno v: Geophysical Research Letters. 5:687-690

The region of plasma flow and electric field reversal in the late evening auroral oval was observed simultaneously by auroral radar and by rocket. A strong, 30-50 mV/m, northward electric field was measured in the southern part of the observing regio

Observations of magnetohydrodynamic waves on the ground and on a satellite

Autor: Carol G. Maclennan, Hiroshi Fukunishi, Louis J. Lanzerotti, L. J. Cahill

Publikováno v: Journal of Geophysical Research. 81:4537-4545

A comparison is made of magnetohydrodynamic waves observed near the equator on Explorer 45 and at an array of ground stations in the northern hemisphere and at their conjugate station at Siple, Antarctica. The data comparisons strongly support the no

Storm time Pc 5 magnetic pulsation at the equator in the magnetosphere and its latitude dependence as measured on the ground

Autor: Louis J. Lanzerotti, C. C. Lin, L. J. Cahill, H. Fukunishi

Publikováno v: Journal of Geophysical Research. 79:2420-2426

A discussion is presented of a Pc 5 magnetic pulsation event observed at L ∼5.5 at the equator in the magnetosphere and at four ground stations in the vicinity of the foot of the field line through the satellite. A large degree of similarity is obs
