Notes. Event date and flare onset time and location are given. These times and locations are taken from the SERPENTINE Events Catalog (Dresing et al. 2024). Entries marked with

^(*)

are taken from Khoo et al. (2024) rather than the SERPENTINE catalogue due to data availability. Event magnitude proxies such as flare class, CME speed and maximum peak flux, $I_{p, 25}^{\max}$ $I_{p,25}^{\mathrm{max}}$ , values are given. Flare classes and $I_{p, 25}^{\max}$ $I_{p,25}^{\mathrm{max}}$ values are also taken from SERPENTINE. $I_{p, 25}^{\max}$ $I_{p,25}^{\mathrm{max}}$ values are the maximum proton peak flux for the ∼25 MeV channel, across the 4 observing spacecraft we use. CME speeds are plane-of-sky speeds from LASCO. Where more than one CME is associated, the largest plane-of-sky LASCO value is used.
