TL;DR: In this article, a high-time resolution Neutron Monitor Database (NMDB) has started to be realized in the frame of the Seventh Framework Programme of the European Commission.
Journal ArticleDOI
Magnetospheric effects in cosmic rays during the unique magnetic storm on November 2003
A. V. Belov,L. Baisultanova,E. A. Eroshenko,Helen Mavromichalaki,Victor Yanke,V. Pchelkin,Christina Plainaki,G. Mariatos +7 more
TL;DR: In this paper, the authors evaluated the geomagnetic effect in cosmic rays due to changes in the magnetosphere on 20 November 2003 using data from the worldwide neutron monitor network and the global survey method.
Journal ArticleDOI
Proton Enhancements and Their Relation to the X-Ray Flares During the Three Last Solar Cycles
TL;DR: In this paper, a broad range of phenomenology relating proton events to flares was investigated, including correlations of occurrence, intensities, durations and timing of both the particle event and the flare as well as the role of the heliographic location of the designated active region.
Journal ArticleDOI
Modeling ground level enhancements: Event of 20 January 2005
TL;DR: In this article, a ground level enhancement model for getting the broadest possible picture, as well as for understanding the physics of solar cosmic ray particles under extreme solar conditions, is proposed.
Journal ArticleDOI
Coronal Mass Ejections and Non-recurrent Forbush Decreases
A. V. Belov,A. A. Abunin,Maria Abunina,E. A. Eroshenko,V. A. Oleneva,Victor Yanke,Athanasios Papaioannou,Helen Mavromichalaki,Nat Gopalswamy,Seiji Yashiro +9 more
TL;DR: In this article, the authors investigated the connection between CME manifestations and non-recurrent Forbush decreases (FDs) and used specially processed data from the worldwide neutron monitor network to pinpoint the characteristics of the recorded FDs together with CME-related data from a detailed online catalog based upon the Solar and Heliospheric Observatory (SOHO)/Large Angle and Spectrometric Coronagraph (LASCO) data.
