Abstract
An M6.5-class flare was observed at N12E56 on the solar surface at 16:06 U on July 8, 2014. In association with the flare, two neutron detectors located at high mountain locations, Mt. Sierra Negra in Mexico and Mt. Chacaltaya in Bolivia, recorded two neutron pulses, separated approximately by 30 min. Moreover, enhancements were also observed by the solar neutron detector onboard the International Space Station. We analyzed these data and contrasted them with solar images from the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory. From the existing evidence, we noticed that the production mechanism of neutrons cannot be explained by a single model; at least one of the enhancements can be explained by an electric field generated by the collision of magnetic loops and the other by the shock acceleration mechanism at the front side of the CME.
