Simultaneous Observation of Solar Neutrons from the ISS and High Mountain Observatories in association with a flare on July 8, 2014

TL;DR

This study reports simultaneous detection of solar neutrons from both space and high mountain observatories during a solar flare, providing insights into high-energy particle emissions and their origins.

Contribution

It presents the first simultaneous observation of solar neutrons from the ISS and ground-based observatories during a specific solar flare, linking neutron enhancements to high-energy protons.

Findings

Detection of neutron enhancements at ISS and mountain observatories

Proposed scenario of high-energy protons and neutrons production

Correlation with ultraviolet observations from SDO

Abstract

An M6.5-class flare was observed at N12E56 of the solar surface at 16:06 UT on July 8, 2014. In association with this flare, solar neutron detectors located on two high mountains, Mt. Sierra Negra and Chacaltaya and at the space station observed enhancements in the neutral channel. The authors analysed these data and a possible scenario of enhancements produced by high-energy protons and neutrons is proposed, using the data from continuous observation of a solar surface by the ultraviolet telescope onboard the Solar Dynamical Observatory (SDO).
