The EU Horizon2020 project EUHFORIA 2.0 aims at developing an advanced space weather forecasting tool, combining the MHD solar wind and CME evolution model EUHFORIA[1] with the Solar Energetic Particle (SEP) transport and acceleration model PARADISE[2]. We will first introduce EUHFORIA and PARADISE and then elaborate on the plans of the EUHFORIA 2.0 project which will address the...
Global magnetic field models use as input synoptic data, which usually show "aging effects" as the 360° information cannot be simultaneously gathered. Most uncertainties come from the far-side which can only be estimated using synoptic charts, surface flux-transport models, or data from helioseismology, however, these are naturally hard to verify.
We present a new method to estimate the...
Large gradual solar energetic particle (SEP) events associated with high-energy protons (up to tens of GeV) can cause hazardous space weather conditions at Earth, pose a severe radiation risk for crewed spaceflight and a significant threat to near-Earth technological assets. We currently do not understand where the SEP seed population originates from and what specific features of a solar...
The 3D MHD modeling is a powerful tool to investigate the physical process responsible for the formation and evolution of the heliosphere and the solar wind. To fully understand the role of each physical ingredient making the model correct, we need a validation process where the output from the simulations are quantitatively compared to the observational data. In this work, we present the...
We study the evolution of the normalized emerging, shearing and total magnetic helicity components for 14 flaring and 14 non-flaring active regions (ARs) using Spaceweather Helioseismic Magnetic Imager Active Region Patches vector magnetic field data (each of the selected AR contains the most complex δ-type spot). Wavelet analysis was performed for each AR. Then we looked for peaks in the...
The solar radio flux at F10.7 and F30 cm is required by most models characterizing the state of the Earth’s upper atmosphere, such as the thermosphere and ionosphere, to specify satellite orbits, re-entry services, collision avoidance maneuvers, and modeling of the space debris evolution. We develop a method called RESONANCE (Radio Emissions from the Sun: ONline ANalytical Computer-aided...
