Energetic electron observations of magnetospheric boundaries using the imaging electron spectrometers on Cluster and Polar

Grande, M.; Davies, J. A.; Daly, P. W. +7 more

Electrons with energies of several tens to several hundreds of keV provide a powerful diagnostic for the acceleration processes associated with magnetospheric boundaries and phenomena. Electrons of these energies can be detected by the imaging electron spectrometer (IES) component of the RAPID experiment onboard each of the quartet of Cluster spac…

Determining the astronomical refraction and building the radio wave refractive delay model measured (II) - Using Hipparcos Catalogue as working catalogue

Yang, Lei; Tie, Qiong-Xian; Li, Bin-Hua +2 more

Demands on the working catalogue when determining the astronomical refraction and influences of systematic error of the catalogue are related. And the systematic error of the FK5 with respect to Hipparcos Catalogue is put forward so as to explain why all the earlier star catalogues are inapplicable to refraction measurement. The characteristic of …

Third San Juan photoelectric astrolabe catalogue (CPASJ3)

Zhao, G.; Alonso, E.; Manrique, W. T. +9 more

Resulting from the cooperation between Beijing, San Juan and La Plata Astronomical Observatories, the photoelectric astrolabe Mark II(PAII) of the Beijing Astronomical Observatory was moved and installed at the San Juan Observatory, Argentina in January, 1992 for observations of stars in the southern hemisphere. Using the data observed with the in…

New Gamma Ray sources discovered by INTEGRAL

Combi, J. A.

One of the strategic objective of the INTEGRAL mission is a regular survey of the galactic plane complemented by a deep exposure of the Galactic Centre. This study is carrying out by the imaging capability of IBIS, which allows the detection of sources at the mCrab level with an angular resolution of 12 arcmin and a point souce location accuracy o…

Approaching Xanadu: Cassini-Huygens Examines Titan

Owen, Tobias

Huygens' January 14 landing on the surface of Titan was a great accomplishment, showing us never-before-seen views of the mysterious moon. But the in-depth examination of the intriguing moon has only just begun. Scientists are still studying Huygens' data, and the Cassini orbiter is completing the first year of its 4-year tour of the Saturnian sys…

Cassini Cosmic Dust Analyser Data V1.0

Kempf, S.; Srama, R.; Altobelli, N.

The Cosmic Dust Analyzer (CDA) is an instrument on the Cassini Orbiter that studies the physical properties of dust particles hitting the detector. This data set includes all data from the CDA with the exception of the High Rate Detector (HRD).

The Sun's Fury In Three Dimensions

Simpson, Sarah

The Ulysses spacecraft's unique orbit over the solar poles gives scientists otherwise unattainable insight into the driving forces behind space weather.

Radio emission observed in decimetric waves associated with the onset of CMEs

Fernandes, F. C. R.; Madsen, F. R. H.; Sawant, H. S. +3 more

Since the first observations by Skylab and SMM satellites coronal mass ejections (CME) have been more and more investigated. However, until now their origin and trigger mechanism remain an open question no matter if they are associated to flares or not. Recent observations over a broad spectrum suggest that flare energy is released in regions from…
