The large longitudinal spread of solar energetic particles during the January 17, 2010 solar event

We investigate multi-spacecraft observations of the January 17, 2010 solar energetic particle event. Energetic electrons and protons have been observed over a remarkable large longitudinal range at the two STEREO spacecraft and SOHO suggesting a longitudinal spread of nearly 360 degrees at 1AU. The flaring active region, which was on the backside of the Sun as seen from Earth, was separated by more than 100 degrees in longitude from the magnetic footpoints of each of the three spacecraft. The event is characterized by strongly delayed energetic particle onsets with respect to the flare and only small or no anisotropies in the intensity measurements at all three locations. The presence of a coronal shock is evidenced by the observation of a type II radio burst from the Earth and STEREO B. In order to describe the observations in terms of particle transport in the interplanetary medium, including perpendicular diffusion, a 1D model describing the propagation along a magnetic field line (model 1) (Dr\"oge, 2003) and the 3D propagation model (model 2) by (Dr\"oge et al., 2010) including perpendicular diffusion in the interplanetary medium have been applied, respectively. While both models are capable of reproducing the observations, model 1 requires injection functions at the Sun of several hours. Model 2, which includes lateral transport in the solar wind, reveals high values for the ratio of perpendicular to parallel diffusion. Because we do not find evidence for unusual long injection functions at the Sun we favor a scenario with strong perpendicular transport in the interplanetary medium as explanation for the observations.Comment: The final publication is available at http://www.springerlink.co

DEVELOPMENT OF PROFESSIONAL EDUCATION IN THE FIELD OF ECOLOGICAL MANAGEMENT AND AUDIT IN THE CONDITIONS OF A NEOCLASSICAL ECONOMIC PARADIGM

In article the current state of professional education in the field of ecological management and audit is considered, formation and which development takes place in conditions of domination of the neoclassical economic theory. The criticism of the designated theory as insolvent is given in modern sociocultural conditions. The essence of ecological management and audit as effective mechanisms of greening of economic activity is opened. The importance of professional education in the field of ecological management and audit in modern conditions is proved. The conceptual model of professional education in the field of ecological management and audit is characterized. Designing of model is carried out taking into account external factors: values of society, social and economic conditions, an ecological situation, tendencies of development of ecological science and the theory of management, modern paradigms of development of professional education, and also social and personal requirements forming valuable and target, structural and substantial, procedurally - its technological parties
