CMEs and SEPs During November–December 2020: A Challenge for Real‐Time Space Weather Forecasting

Predictions of coronal mass ejections (CMEs) and solar energetic particles (SEPs) are a central issue in space weather forecasting. In recent years, interest predictions has expanded to include impacts at other planets beyond Earth as well spacecraft scattered throughout the heliosphere. this sense, scope science now encompasses whole heliospheric system, multi-point measurements transients can provide useful insights validations for prediction models. work, we aim analyse inner context between two eruptive flares that took place late 2020, i.e. M4.4 flare November 29 C7.4 December 7. This period is especially interesting because STEREO-A was located ~60{\deg} east Sun-Earth line, giving us opportunity test capabilities "predictions 360{\deg}" using remote-sensing observations from Lagrange L1 L5 points input. We simulate CMEs were ejected during our SEPs accelerated by their shocks WSA-Enlil-SEPMOD modelling chain four sets input parameters, forming "mini-ensemble". validate results in-situ six locations, including Mars. find that, despite some limitations arising models' architecture assumptions, shock-accelerated be reasonably studied forecast real time least out several tens degrees away eruption site tools employed here.
