Solar Wind streams, acting as a background, govern the propagation of coronal mass ejections in the heliosphere and drive geomagnetic storm activities. Therefore, predictions of the solar wind parameters are the core of space weather forecasts. Also, structure and dynamics of the heliospheric magnetic field (HMF) are key to understanding the solar wind flow. Typically, line-of-sight...
An assessment of the long-term behaviour of the solar wind is of paramount importance to understand the nature of its relationship with solar activity cycles, but also to evaluate its long-lasting effects on Earth. Understanding the long-term solar wind properties also helps putting in a different perspective space weather events on shorter time scales and extreme events. In order to connect...
Coronal mass ejections (CMEs) are one of the major sources for space weather disturbances. If the magnetic field inside an Earth-directed CME or its associated sheath region has a southward-directed component (Bz), then it interacts effectively with the Earth’s magnetosphere, leading to severe geomagnetic storms. Therefore, it is crucial to predict the strength and direction of Bz inside...
Coronal Mass Ejections (CMEs) are triggered by kinetic-scale magnetic field topologies within the solar corona and evolve into large-scale structures with sizes of the order of the heliosphere itself. In this paper, we discuss the development of 3-D magnetohydrodynamic (MHD) simulations starting at the solar surface and extending outward through the solar corona and into the inner...
Within the last years artificial intelligence (AI) excelled in many disciplines, providing major advances in image processing techniques with the use of deep learning. As part of the EU H2020 SOLARNET project we develop methods for the anticipated Solar Physics Integrated Network Group (SPRING), a global network of ground-based solar telescopes. In this presentation we discuss the application...
The Solar Activity Magnetic Monitor (SAMM) Network (SAMNet) is an international consortium of ground-based solar telescope stations. SAMNet, at its full capacity, will continuously monitor the intensity, magnetic and Doppler velocity fields at multiple heights in the solar atmosphere from the photosphere to the upper chromosphere. SAMM sentinels are equipped with a cluster of identical...
Solar energetic protons in solar cycle 24 accompanied by EUVI waves from SDO/AIA are analysed and presented. Multi-energy proton data from 10s to 130s MeV from the SOHO/ERNE instrument is used. Pearson and partial correlation analysis between the proton intensities and flare or CME parameters is performed. Additionally, the interplanetary conditions are inspected in terms of shock waves...
