From: Unusual enhancement of ~ 30 MeV proton flux in an ICME sheath region
Enlarged view of the enhanced proton flux and associated plasma parameters. a–d Corrected proton flux measured by GOES at energies ~ 2.5, ~ 6.5, ~ 11.6, and ~ 30.6 MeV. e, f Energetic proton flux measured by SOHO in the 26–32 MeV range and by Wind in the 19–28 MeV range. g–k Various parameters of the solar wind measured by Wind. g Proton number density. h Proton flow speed. i Magnetic field magnitude (|B|). j Magnetic field latitudinal angle (θB). k Magnetic field longitudinal angle (φB). The data are shown in the Geocentric Solar Ecliptic (GSE) coordinate in which X-points toward the Sun, Z parallel to the ecliptic pole, and Y completing the right-hand system (toward dusk)
