When such a trap passes by Earth, enhanced electron fluxes are observed. The flux peaks are not high; they are only visible clearly at low background, i.e. low solar activity. We compare electron flux observations during subsequent solar activity minima. A particularly long series was observed during the last minimum in 2007-2009 with an average period of about 26 days, instead of 27.3 days expected - the synodic period of the Earth. During other solar activity minima the period also differs from it by 1-2 days suggesting the existence of a complicated structure consisting of magnetic traps which allows Jovian electrons to arrive at Earth irrespective of the relative position of Jupiter and Earth. The size of traps, their longitudinal extension and the lifetime of electrons is investigated together with the magnetic field and its variability. The variation of the periodicity of Jovian electron fluxes due to co-rotation with the Sun is connected to the variability of the magnetic structure of the traps in the course of one solar rotation (≈ 25 days). In numerical simulations assuming perfect co-rotation and Jupiter as a moving source in the co-rotating frame a combined effect of the CIR and magnetic connection is obtained and fitted to the observations.}, year = {2014} } @CONFERENCE{MTMT:2846360, title = {Multispacecraft study on the geometry of mirror type magnetic oscillations in the magnetosheath}, url = {https://m2.mtmt.hu/api/publication/2846360}, author = {Tátrallyay, Mariella and Erdős, Géza}, booktitle = {40th COSPAR Scientific Assembly}, unique-id = {2846360}, abstract = {Linearly polarized magnetic field oscillations identified as mirror mode waves are frequently present in the magnetosheath. Cluster observations are used to investigate the three-dimensional structure of these wave trains based on case studies. The reconstruction of the geometry of the magnetic structures is based on the assumption that they are frozen into the plasma and they are elongated in the average direction of the field. The development of the structures from the bow shock to the magnetopause is investigated whether magnetic depressions first form as planar waves and they decay to more axially symmetric structures around the main magnetic field in the inner magnetosheath. Correlation between the magnetic field profiles measured across the magnetic dips (or peaks) by the four spacecraft allows to determine the wave propagation velocity. When comparing the velocity of the magnetic structures determined by triangulation with the plasma velocity measured by the CIS instrument, the assumption can be tested whether these structures are frozen into the plasma. The relation between the direction of the wave vector and the bow shock normal is investigated addressing the problem whether the generation of the waves behind the bow shock is part of the shock formation process.}, year = {2014} } @CONFERENCE{MTMT:2846359, title = {The influence of magnetosheath magnetic field line stress and pressure on the geomagnetopause position and shape}, url = {https://m2.mtmt.hu/api/publication/2846359}, author = {Verigin, M and Tátrallyay, Mariella and Erdős, Géza and Bezrukikh, V and Remizov, A and Kotova, G}, booktitle = {40th COSPAR Scientific Assembly}, unique-id = {2846359}, abstract = {Solar wind ram pressure onto the magnetopause is undoubtedly the main factor providing the geomagnetosphere formation. Two complementary factors were also recently revealed in observations. These are the magnetotail magnetic field line tension and pressure. Magnetic field line tension leads to the clock angle dependency of the geomagnetotail terminator cross-section in the reference frame rotating with IMF transversal component (Verigin et al., Geomagn. & Aeron., 2009). While the magnetic field pressure leads to magnetopause movement towards the Earth when the IMF cone angle approaching ppi/2 (Dušík et al., J. Geophys. Res., 2010). It is shown that the influence of the curved magnetic field line stress on the magnetosheath plasma flow is 2DDelta/R times less than the influence of the magnetic field line pressure, where DDelta is the magnetosheath thickness and R is the magnetic field lines curvature radius. New analytic proxy for magnetosheath stagnation pressure is proposed in the talk as a function of the solar wind, ram pressure, IMF direction, sonic, and Alfvenic Mach numbers. Geomagnetopause model based on the measurements of Prognoz’/Intrerball’ orbiters is updated taking into account the new stagnation pressure proxy.
