The Magnetospheric cusps: A Summary
Zong, Q. G.; Fritz, T. A.
The polar cusps of the magnetosphere are key regions for the transfer of mass, momentum, and energy from the solar wind into the magnetosphere. Understaning these key regions and the dynamical interactions that occur there are fundamentally important to determining the physical nature of the magnetosphere. In this paper we try to summarize many of…
Observations of a Unique Cusp Signature at Low and Mid Altitudes
Winningham, J. D.; Balogh, A.; Fazakerley, A. N. +7 more
Observations of a unique cusp feature at low and mid altitudes are reported. This feature has a consistent double-peaked or “V”-shaped structure at the equatorward edge of high-latitude particle precipitation flux, and is predominantly present for high IMF By conditions. The observations are consistent with the Crooker (‘A split separat…
Energetic Particles Observed in the CUSP Region During a Storm Recovery Phase
Reme, H.; Korth, A.; Daly, P. +4 more
In this paper we report energetic ion behavior and its composition variations observed by the Cluster/RAPID instrument when the spacecraft was travelling in the high latitude magnetospheric boundary region on the day of the 31 March, 2001, strongest magnetic storm in the past 50 years. The Dst index reached ‑360 nT at about 09:00 UT. During its ea…
Earth Rotation Parameters 1899.7 :1992.0 After Reanalysis Within The Hipparcos Frame
Vondrák, Jan.
Earth rotation parameters (ERP) in the interval 1899.7-1992.0 are obtained from re-analysis of the observed latitude/universal time variations by optical astrometry. Hipparcos Catalogue is used to define the celestial reference frame, within which the ERP are described, with special care devoted to 'problematic' double and/or multiple stars. The t…
