Resumen:

We identified three neutron monitor stations in the American sector that registered the impulsive phase of the GLE event on November 2, 1992 (event 54) and constructed an estimate for the rigidity spectrum of the high-energy particles present on the event computing each station?s median response energy for solar particles taking into account the particular geomagnetic conditions during the event that modify the normal cut-off rigidity for each of the sites. Our result complements a previously reported low-energy spectrum for the gradual phase of the same event. © 2013 Sociedade Brasileira de Fisica. All Rights Reserved.
