Predicting CME Arrivals with Heliospheric Imagers from L5: A Data Assimilation Approach
Tanja Amerstorfer, Justin Le Louëdec, David Barnes +5
The Solar TErrestrial RElations Observatory (STEREO) mission has laid a foundation for advancing real-time space weather forecasting by enabling the evaluation of heliospheric imag…
Understanding the effects of spacecraft trajectories through solar coronal mass ejection flux ropes using 3DCOREweb
Hannah Theresa Rüdisser, Andreas Jeffrey Weiss, Justin Le Louëdec +4
This study investigates the impact of spacecraft positioning and trajectory on in situ signatures of coronal mass ejections (CMEs). Employing the 3DCORE model, a 3D flux rope model…
Writhed Analytical Magnetic Flux Rope Model
Andreas J. Weiss, Teresa Nieves-Chinchilla, Christian Möstl +3
Observations of magnetic clouds, within interplanetary coronal mass ejections (ICMEs), are often well described by flux rope models. Most of these assume either a cylindrical or to…
Radial Evolution of the April 2020 Stealth Coronal Mass Ejection between 0.8 and 1 AU -- A Comparison of Forbush Decreases at Solar Orbiter and Earth
Johan L. Freiherr von Forstner, Mateja Dumbović, Christian Möstl +40
Aims. We present observations of the first coronal mass ejection (CME) observed at the Solar Orbiter spacecraft on April 19, 2020, and the associated Forbush decrease (FD) measured…
Coronal Magnetic Structure of Earthbound CMEs and In situ Comparison
Erika Palmerio, Emilia K. J. Kilpua, Christian Möstl +6
Predicting the magnetic field within an Earth-directed coronal mass ejection (CME) well before its arrival at Earth is one of the most important issues in space weather research. I…
Forward modeling of coronal mass ejection flux ropes in the inner heliosphere with 3DCORE
Christian Möstl, Tanja Amerstorfer, Erika Palmerio +7
Forecasting the geomagnetic effects of solar storms, known as coronal mass ejections (CMEs), is currently severely limited by our inability to predict the magnetic field configurat…
ElEvoHI: a novel CME prediction tool for heliospheric imaging combining an elliptical front with drag-based model fitting
Tanja Rollett, Christian Möstl, Alexey Isavnin +4
In this study, we present a new method for forecasting arrival times and speeds of coronal mass ejections (CMEs) at any location in the inner heliosphere. This new approach enables…
Arrival time calculation for interplanetary coronal mass ejections with circular fronts and application to STEREO observations of the 2009 February 13 eruption
C. Möstl, T. Rollett, N. Lugaz +11
A goal of the NASA STEREO mission is to study the feasibility of forecasting the direction, arrival time and internal structure of solar coronal mass ejections (CMEs) from a vantag…
The size distribution of magnetic bright points derived from Hinode/SOT observations
D. Utz, A. Hanslmeier, C. Möstl +3
Context. Magnetic Bright Points (MBPs) are small-scale magnetic features in the solar photosphere. They may be a possible source of coronal heating by rapid footpoint motions that…
