Low-Energy Anomalous Cosmic Rays in the Ecliptic Plane: 1-5 AU
Lanzerotti, L. J.; Maclennan, C. G.
Anomalous cosmic-ray (ACR) oxygen (O) fluxes in the energy range 0.5-5.0 MeV nucleon-1 were measured in the ecliptic plane at 1 and 5 AU in 1997 and 1998. Using measurements from essentially identical instruments on the Advanced Composition Explorer (ACE) and Ulysses spacecraft, we were able to monitor the decrease with time of the ACR …
ISOPHOT Far-Infrared Survey of Nearby Molecular Clouds
Lemke, Dietrich; Mattila, Kalevi; Haikala, Lauri +2 more
We present results of a far-infrared molecular cloud mapping program which utilizes the PHT-P photometer and PHT-C cameras of the ISOPHOT instrument. ISO has enabled us to study the emission of very cold dust, Td < 15 K. The multi-wavelength observations between 3.6-200 µm allow to discern emission of different grain components, and …

A Search for Extended Line Emission from Broad Absorption Line QSOS
Kriss, Gerard A.; Tsvetanov, Zlatan; Telfer, Randal C.
We have obtained Hubble Space Telescope NICMOS snapshot images of 10 broad absorption line (BAL) QSOs and four radio-quiet non-BAL QSOs to search for extended narrow-line regions. For each object, we obtained an image in the F160W filter and a narrowband image in either Hα, Hβ, or [O II]. We find no detections of extended narrow-line emission in t…
Location of the activity responsible for the appearance of coronal mass ejections and the sites of their ejection from the solar surface.
Shilova, N. S.
The white-light films of coronal mass ejections for April - May, 1998 (SOHO LASCO C2, C3), retrieved from Internet, are considered. The positions of active regions on visible and back sides of the Sun for each day are studied. It is shown that a region of large flare can be localized at a distance not less than the solar radius from the place wher…
ISO Observations of the Planetary Nebula Lindsay 305 in the Small Magellanic Cloud
Tanabé, Toshihiko; Sauvage, Marc; Vansevičius, Vladas +1 more
We present ISO (Infrared Space Observatory) observations of the planetary nebula Lindsay 305 (L 305) in the Small Magellanic Cloud. L 305 is very prominent in the ISOCAM frames at 6.75 and 11.5 mu m, although it is under the detection limit at 4.5 mu m. The obtained spectral energy distribution shows a strong mid-IR excess, which, depending on the…
Detection of moving clusters by a method of cinematic pairs
Khodjachikh, M. F.; Romanovsky, E. A.
The algorithm of revealing of pairs stars with common movement is offered and is realized. The basic source is the catalogue HIPPARCOS. On concentration of kinematic pairs it is revealed three unknown earlier moving clusters in constellations: 1) Phe, 2) Cae, 3) Hor and, well known, in 4) UMa are revealed. On an original technique the members of c…
A fast calculation algorithm for the charge transfer loss in CCDs
Strüder, L.; Krause, N.; Soltau, H. +3 more
Charge transfer loss due to deep level traps in CCDs is a common phenomenon. In single-photon counting CCDs for X-ray detection, the charge loss results in a degradation of spectroscopic resolution. The transfer loss of a signal depends on various parameters like temperature, number of transferred charges, number of charges in the preceding signal…
Uses of the V Magnitudes Reobserved with the Hipparcos & Tycho Photometers Outside the Earth's Atmosphere

Reduction of the measurements of the FON program plates with the use of USNO act data
Yatsenko, A. I.
The method of reduction of plate measurements within the northern sky photographic survey program (FON) is described. The ACT Reference Catalogue was employed for the reductions of positions. The BJ magnitudes from the Tycho Catalogue were used for the calibration of the measured diameters of stars. The GSC1.1 catalogue was used to dete…
