Observation of maximum injection upper limit for energetic proton events according to SOHO/ERNE measurements
We analyzed 25 solar energetic particle events, with energies ∼ 1 − 100 MeV, observed with ERNE instrument onboard Solar and Heliospheric Observatory (SOHO) and found that all of the solar energetic particlse were associated with coronal mass ejections, observed with LASCO/SOHO. The observational da...

This might indicate that the upper limit of maximum acceleration by the shock waves decreases earlier as we go higher in the proton energy level. |
