N2 - At the 33rd ICRC, we reported the possible detection of solar gamma rays by a ground level detector and later re-examined this event. On March 7, 2011, the solar neutron telescope (SNT) located at Mt. Sierra Negra, Mexico (4,600 m) observed enhancements of the counting rate from19:49 to 20:02 UT and from 20:50 to 21:01 UT. The statistical significance was 9.7σ and 8.5σ, respectively. This paper discusses the possibility of using this mountain detector to detect solar gamma rays. In association with this event, the solar neutron detector SEDA-FIB onboard the International Space Station has also detected solar neutrons with a statistical significance of 7.5σ. The FERMI-LAT detector also observed high-energy gamma rays from this flare with a statistical significance of 6.7σ. We thus attempted to make a unified model to explain this data. We also report on another candidate for solar gamma rays detected on September 25th, 2011 by the SNT located in Tibet (4,300 m) from 04:37 to 04:47 UT with a statistical significance of 8.0σ (by the Li-Ma method).
