Solar Neutron Telescopes and Earth orbiting spacecraft observations of the March 7th and September 25th of 2011 events: solar neutron and gamma-rays
Abstract
Being associated with a high energy gamma-ray flux with statistical significance of 6.5_ observed by the Large Area Telescope of the Fermi orbiting observatory (FERMI-LAT) on March 7, 2011, the Space Environment Data Acquisition Equipment (SEDA-FIB) onboard the International Space Station (ISS) registered solar neutrons with a statistical significance of 7.5_. The Solar Neutron Telescope (SNT) in operation at Mt. Sierra Negra, Mexico (4,600 m) detected increases of the fluxes in a channel registering neutral particles, not necessarily neutrons, from 19:49 to 20:02 UT and from 20:50 to 21:01 UT. The significances were 9.7_ and 8.5_, respectively. On September 25th, 2011 the SNT located at Yangbajing in Tibet (4,300 m) observed signals very similar to those of the referred Sierra Negra event from 04:37 to 04:47 UT with a statistical significance of 8.0_ (by the Li-Ma method)._Details of both events are presented in this paper in an effort to produce a unified model that can explain these data. We think that these mountain detectors registered gamma-rays from the Sun and_a plausible physical explanation of the results is provided.
