Abstract content

Strong signals of energetic neutrons associated with the solar flare of 7 September 2005 were detected by using the Solar Neutron Telescopes located at Mt. Chacaltaya in Bolivia and Mt. Sierra Negra in Mexico, Neutron Monitors located at Mt. Chacartaya and Mexico City. The observed profiles indicate a continuous emission of neutrons. In this paper, we present the results of combined analysis of the SNT and NM data to obtain emission profile and spectrum of the neutrons. Especially the SNT data of the different energy threshold gives an unprecedented capability of the analysis. We also discuss an association with the electromagnetic radiations and neutron emission models.
