The Cosmic Ray Ground Level Enhancement of 6 November 1997

Abstract

The relativistic solar proton event of 6 November 1997 resulted in the first ground-level enhancement (OLE) of solar cycle 23. The earliest onset was around 1215 UT but was up to 15 minutes later at some neutron monitor locations. The time of maximum intensity also varied significantly over the world-wide neutron monitor network. The modeled particle distributions and spectra are presented. The apparent particle arrival direction is found to be largely consistent with propagation outward from the sun along interplanetary magnetic field lines.
