Laitinen, T.; Vainio, R.; Valtonen, E. +7 more

The observations of the ERNE instrument on-board the SOHO spacecraft are analysed. The main period under study is from the beginning of May till mid-October 1996. Only very small energetic particle events were observed. A comparison of the ERNE measurements with energetic particle observations during the two previous solar minima indicates that th…

Clumpy Structure and Polarization in NGC 1068

DOI: 10.1023/A:1000588619925 Bibcode: 1997Ap&SS.248..277K

Kishimoto, M.

The polarization map from the HST archival data of the imaging polarimetry for NGC 1068 is analyzed. In the HST images, the central few arcsecond region seems to consist of several clumps, and if we extract the polarization of the clumps separately, the viewing angle of each clump can be determined. This enables us to have a three-dimensional view…

Magnetic mapping of auroral signatures of comet SL9 in the Jovian magnetosphere

Dunlop, M.; Prangé, R.; Maurice, S. +2 more

The electrodynamic interaction of comet Shoemaker-Levy 9 (SL9) with the Jovian magnetosphere gave rise to the detection of several unique phenomena in the UV, X-ray and radio wavelength ranges. Among them, the detection of an unusual FUV bright spot in Hubble Space Telescope images of the southern polar cap on July 20, just before P2 collision, ma…

High-Resolution V, I, and K-Band Imaging of Faint Field Galaxies from the HST Medium-Deep Survey

Windhorst, Rogier A.; Close, Laird M.; Mutz, Steven B. +2 more

We present infrared and optical data for 13 galaxies with 16.0≤I≤21 mag previously observed with the Hubble Space Telescope as part of a study of 300 galaxies from the Medium-Deep Survey. We observed four of these galaxies at the Steward Observatory 90" and 61" telescopes in the K band (λ_eff=2.2 µm) with a tip-tilt secondary mirro…

Recurrences of interplanetary interaction regions at southern solar latitudes and approximate harmonics

DOI: 10.1016/S0273-1177(97)00489-4 Bibcode: 1997AdSpR..20..103T

Lanzerotti, L. J.; Maclennan, C. G.; Thomson, D. J.

A series of low energy (~60 keV/nucl to several MeV/nucl) interplanetary particle enhancements was measured by the HI-SCALE instrument on the Ulysses spacecraft during the first approximately two-thirds of 1993. At this time Ulysses was located between ~4.3 - 5.0 AU and climbing from ~ 23 deg to ~40 deg south heliolatitude. Spectral analyses of th…
