Record #150895:

The cosmic ray asymptotic directions for Station Oulu in the magnetic field of the Tsyganenko 1989 model / Olga Danilova, Marta Tyasto, Hannu Konanen, Pekka Tanskanen.

Title: The cosmic ray asymptotic directions for Station Oulu in the magnetic field of the Tsyganenko 1989 model / Olga Danilova, Marta Tyasto, Hannu Konanen, Pekka Tanskanen.
Author(s): Danilova, Olga.
Tyasto, Marta.
Konanen, Hannu.
Tanskanen, Pekka.
Date: 1999.
In: Geophysica. (1999.), Vol. 35(1-2) (1999)
Abstract: Using Tsyganenko's magnetospheric model, directions were calculated for 17 h GMT 23 Jun 1990 at summer solstice, when angle between Earth's geomagnetic axis and perpendicular to ecliptic plane reaches maximum. Analyses show that directions for particles with rigidities below 1 GV strongly depend on disturbance level of magnetosphere. Such particles are asymptotically concentrated within narrow band along curves independent of zenith or azimuth angles.
