Comparing the Properties of ICME-Induced Forbush Decreases at Earth and Mars
Johan L. Freiherr von Forstner, Jingnan Guo, Robert F. Wimmer-Schweingruber +9
Forbush decreases (FDs), which are short-term drops in the flux of galactic cosmic rays, are caused by the shielding from strong and/or turbulent magnetic structures in the solar w…
Tracking and Validating ICMEs Propagating Toward Mars Using STEREO Heliospheric Imagers Combined With Forbush Decreases Detected by MSL/RAD
Johan L. Freiherr von Forstner, Jingnan Guo, Robert F. Wimmer-Schweingruber +7
The Radiation Assessment Detector (RAD) instrument onboard the Mars Science Laboratory (MSL) mission's Curiosity rover has been measuring galactic cosmic rays (GCR) as well as sola…
Modeling the evolution and propagation of the 2017 September 9th and 10th CMEs and SEPs arriving at Mars constrained by remote-sensing and in-situ measurement
Jingnan Guo, Mateja Dumbović, Robert F. Wimmer-Schweingruber +13
On 2017-09-10, solar energetic particles (SEPs) originating from the active region 12673 were registered as a ground level enhancement (GLE) at Earth and the biggest GLE on the sur…
Long-lasting injection of solar energetic electrons into the heliosphere
Nina Dresing, Raúl Gómez-Herrero, Bernd Heber +3
The main sources of solar energetic particle (SEP) events are solar flares and shocks driven by coronal mass ejections (CMEs). While it is generally accepted that energetic protons…
Injection of solar energetic particles into both loop legs of a magnetic cloud
Nina Dresing, Raúl Gómez-Herrero, Bernd Heber +4
Each of the two STEREO spacecraft carries a SEPT Instrument which measures electrons and protons. Anisotropy observations are provided in four viewing directions. The SEP event on…
Assessing the Constrained Harmonic Mean Method for Deriving the Kinematics of ICMEs with a Numerical Simulation
Tanja Rollett, Manuela Temmer, Christian Möstl +3
In this study we use a numerical simulation of an artificial coronal mass ejection (CME) to validate a method for calculating propagation directions and kinematical profiles of int…
