MARC recordThe 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. |
