The Alpha Magnetic Spectrometer (AMS-02) with its acceptance of about 0.45 m$^2$ sr, is the largest Solar Energetic Particle (SEP) detector in space. It was installed on the International Space Station (ISS) on May 19, 2011, where it will take data for the duration of the station (~2024). In the first 3 years of operations, AMS-02 detected and measured many events related to short-term solar...

Abstract
23 instrument systems on 7 space flight missions were used during 2014 to examine solar flare activity over the period 15 February 2011 to 26 September 2014 which includes the maximum of sunspot cycle 24. Subsequently additional data from 5 other missions were added to this set. Owing to the increase in research assets available during this period and the use of new orbits and...

Low-energy cosmic rays and solar particles are strongly deflected by Earth's geomagnetic field. Due to the structure of the field a location and direction depend geomagnetic cutoff is apparent. This presentation will present geomagnetic cutoff simulations using the PLANETOCOSMICS software with the IGRF geomagnetic field and the Tsyganenko magnetosphere. The development over time during the...

We report the proton spectrum of two GLEs, 2001 April 15 and 2005 January 20. Using two
instruments, the Climax neutron monitor and the Milagro ground based TeV gamma-ray
telescope, we constructed the spectrum of the highest energy part of the GLE spectrum. The
many available rigidity thresholds in the Milagro instrument, coupled with the nearby Climax
NM, allows one to construct a...
