Analysis of the anomalous event GLE66 on October 29, 2003

Abstract

Event GLE66 (29.10.2003) is a selected study in a series of three GLE events that occurred in the fall of 2003. there was this most powerful magnetic storm and a deep Forbush effect, during which GLE66 occurred. The appearance of the T-05 drilling model of the magnetosphere and the availability of a methodology debugged on dozens of less complex GLE events for solving the problem of achieving results for this complex event. Obtaining the values of the parameters of the cosmic ray flux at subsequent moments of time. A pattern typical of GLE events is observed: the spectrum of observed cosmic rays at the initial phase has an exponential shape, and then ends in a power law. The obtained spectra are in good agreement with measurements of cosmic ray precipitation on spacecraft at lower energies.
