Investigating potential benefits of future sub-L1 missions with STEREO-A
Eva Weiler, Emma E. Davies, Christian Möstl +4
We present the first statistical study of geomagnetic storm forecasting using in situ data from the STEREO-A spacecraft as a sub-L1 monitor. Between November 2022 and June 2024, ST…
Evolution of Coronal Mass Ejection Properties through Superposed Epoch Analysis from 0.2 to 2.2 au
Yakub Olufadi, Nada Al-Haddad, Florian Regnault +6
Coronal mass ejections (CMEs) are explosive and energetic events consisting of strong magnetic structures erupting from the solar corona. We use superposed epoch analysis to invest…
The evolution of CME sheath turbulence from L1 to Earth: Wind and MMS observations of the 2023-04-23 CME
Matthew R. Argall, Li-Jen Chen, Noé Lugaz +5
An interplanetary shock driven by a coronal mass ejection (CME) containing an interval of sub-Alfvénic flow impacted Earth on April 23, 2024. In this article, we analyze the turbu…
First observations of a geomagnetic superstorm with a sub-L1 monitor
Eva Weiler, Christian Möstl, Emma E. Davies +10
Forecasting the geomagnetic effects of solar coronal mass ejections (CMEs) is currently an unsolved problem. CMEs, responsible for the largest values of the north-south component o…
