Warning Time Analysis From SEP Simulations of a Two-Tier REleASE System Applied to Mars Exploration

Posner, A.; Strauss, R. D.

The sudden exposure to energetic protons from solar energetic particle (SEP) events beyond the Earth's magnetosphere and en route to and from Mars can, in extreme cases, lead to acute radiation sickness, an impairing, mission-endangering condition for astronauts. Timely warnings of their impending occurrence may significantly reduce radiation expo…

Application of a Modified Spheromak Model to Simulations of Coronal Mass Ejection in the Inner Heliosphere

Pogorelov, Nikolai V.; Arge, Charles N.; Singh, Talwinder +1 more

The magnetic fields of interplanetary coronal mass ejections (ICMEs), which originate close to the Sun in the form of a flux rope, determine their geoeffectiveness. Therefore, robust flux rope-based models of CMEs are required to perform magnetohydrodynamic (MHD) simulations aimed at space weather predictions. We propose a modified spheromak model…

Space Weather Monitor at the L5 Point: A Case Study of a CME Observed with STEREO B

Mierla, M.; Zhukov, A. N.; Rodriguez, L. +2 more

An important location for future space weather monitoring is the Lagrange point 5 (L5) of the Sun-Earth system. We test the performance of L5 for space weather monitoring using STEREO B observations of an Earth-directed coronal mass ejection (CME), seen as a partial halo by SOHO at L1. STEREO B (located close to L5) continuously tracked the CME. B…
