Ion measurements in the jovian magnetosphere by the ULYSSES EPAC experiment: a comparison between dawn and dusk sectors
Franz, M.; Krupp, N.; Dougherty, M. K. +4 more
We report on results from the EPAC experiment on board the Ulysses spacecraft during the Jupiter Flyby in February 1992. We compare ion anisotropies (E = 0.24-0.77 MeV/N) received on the inbound pass in the noon sector at low magnetic latitudes with those from the outbound pass in the dusk sector at high magnetic latitudes. The results can be summ…
Modulation recovery of high energy electrons: ULYSSES observations
Sierks, H.; Kunow, H.; Heber, B. +5 more
The ULYSSES spacecraft, launched in Oct 1990 near solar maximum, continues its investigation journey toward the southern polar pass during the decaying phase of solar cycle 22. One of the primary aim of its mission, namely the study of the cosmic-ray solar modulation in the three-dimensional heliosphere, has really started when exploring high latt…
Results from the corrected hubble space telescope
Kinney, A. L.
Findings from the refurbished Hubble Space Telescope are presented, including imaging of asymmetrical circumstellar material around pre-main sequence stars in the Orion Nebula, discovery of a triple ring system in the supernova remnant 1987a, and the measurement of high velocity in the central region of the nucleus of the active galaxy M87 which p…
Interplanetary magnetic field during the Giotto encounter and the induced magnetosphere of comet Halley
Neubauer, F. M.; Israelevich, P. L.; Ershkovich, A. I.
The direction of the interplanetary magnetic field (IMF) which governs the orientation of the Halley's magnetosphere was restored. Giotto magnetic and plasma data were represented in the coordinate system rotating with the IMF.
Ultraviolet eclipse observations of an accretion disk wind
Raymond, J. C.; Mason, K. O.; Cordova, F. A. +3 more
We present eclipse time series of ultraviolet Civ 1549Angstroms and Heii line profiles in the spectrum of the nova-like variable UX UMa, obtained using the Goddard High Resolution Spectrometer (GHRS) on board the Hubble Space Telescope (HST). These data provide important new insights into the origin of these mainly wind-formed lines. Specifically,…
