An association of CMEs with solar flares detected by Fermi γ-ray burst monitor during solar cycle 24

Abdel-Sattar, Walid; Mawad, Ramy; Farid, Hussein M.

By performing certain spatial and temporal criteria, we obtained 492 CME events simultaneously associated with GBM solar flare events (hereafter, GBM-flare-CME) from the total number 5123 Gamma-ray Burst Monitor (GBM) solar flares and 15228 Coronal Mass Ejections (CMEs) detected during the solar cycle 24 (2008-2019). Among these 492 events, which …

A new approximate coupling function: The case of Forbush decreases

Xaplanteris, L.; Livada, M.; Mavromichalaki, H. +1 more

We attempt the derivation of a new coupling function between ground level and primary cosmic rays for the case of Forbush decreases. The calculations for the new function are based on basic Quantum Field Theory theoretical tools, something that has not been attempted till now in other widely used cosmic ray coupling functions. The use of Quantum F…
