On the Onset Time of Several SPE/GLE Events: Indications from High-Energy Gamma-Ray and Neutron Measurements by CORONAS-F

Figure 7

Time profiles of selected emissions from the November 4, 2003, flare: (a) hard X-ray measured by Ulysses (blue curve, right 𝑦-axis) and CORONAS-F/SPR-N (black curve, left 𝑦-axis); (b) hard X-rays (40–100 keV) from CORONAS-F/SPR-N; (c) gamma-rays 0.75–2 MeV (black, left 𝑦-axis) and 6–10.5 MeV (green, right 𝑦-axis) from CORONAS-F/SONG; (d) summarized normalized intensity of the 4.4 MeV + 6.1 MeV gamma-lines from INTEGRAL/SPI [53]; (e) gamma-rays >90 MeV (gray, left 𝑦-axis, data are normalized) and neutrons (black, right 𝑦-axis) from CORONAS-F/SONG. Red curve in the bottom panel presents smoothed data on gamma-rays.
