Comparing Long-Duration Gamma-Ray Flares and High-Energy Solar Energetic Particles
G. A. de Nolfo, A. Bruno, J. M. Ryan +10
Little is known about the origin of the high-energy and sustained emission from solar Long-Duration Gamma-Ray Flares (LDGRFs), identified with the Compton Gamma Ray Observatory (CG…
Spectral Analysis of the September 2017 Solar Energetic Particle Events
A. Bruno, E. R. Christian, G. A. de Nolfo +2
An interval of exceptional solar activity was registered in early September 2017, late in the decay phase of solar cycle 24, involving the complex Active Region 12673 as it rotated…
Unexpected cyclic behavior in cosmic ray protons observed by PAMELA at 1 AU
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +50
Protons detected by the PAMELA experiment in the period 2006-2014 have been analyzed in the energy range between 0.40-50 GV to explore possible periodicities besides the well known…
Calibration of the GOES-13/15 high energy proton detectors based on the PAMELA solar energetic particle observations
Alessandro Bruno
The EPEAD and HEPAD instruments on the GOES spacecraft have served over many years as monitors of the solar particles intensities, surveying the Sun and measuring in situ its effec…
Geomagnetically trapped, albedo and solar energetic particles: trajectory analysis and flux reconstruction with PAMELA
A. Bruno, O. Adriani, G. C. Barbarino +59
The PAMELA satellite experiment is providing comprehensive observations of the interplanetary and magnetospheric radiation in the near-Earth environment. Thanks to its identificati…
PAMELA's measurements of geomagnetic cutoff variations during the 14 December 2006 storm
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +55
Data from the Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics (PAMELA) satellite experiment were used to measure the geomagnetic cutoff for high-energy (>80…
