    Poster

    Solar eruptions, such as flares and coronal mass ejections (CME), are key drivers of space weather phenomena. CMEs are large plasma eruptions, with magnetic flux ropes frozen-in the plasma. They can travel within the heliosphere with speeds from a few hundred up to 1000 km/s and can have a profound impact on the near-Earth environment, as well as human activity in space and on ground....

    Turbulence in space and astrophysical plasmas is an intrinsic multiscale phenomenon, which involves nonlinear coupling across different temporal and spatial scales. As a result, the physical mechanisms responsible for the turbulent dissipation and the heating of the plasma below the proton characteristic scales remain largely unknown. In this talk, we will present recent results from a...

    Poster

    The sheath regions driven by coronal mass ejections (CMEs) are large-scale heliospheric structures. Turbulent and compressed sheaths could contribute to the acceleration of charged particles in interplanetary space, but their internal structure and its relation to energization process is still poorly understood. We report here the analysis based on observations by Solar Orbiter, BepiColombo...

    Poster

    Coronal holes (CHs) are regions with open magnetic field topology in the solar corona. They are characterized by lower densities and temperatures compared to the ambient solar environment. Further, they are the source regions of high speed solar wind streams (HSSs), which propagate through the interplanetary space. Throughout the years, many authors have performed statistical studies comparing...

    Poster

    Sunspot areas are important quantities that can be obtained from the analysis of the images of the solar photosphere. In particular, sunspot areas extracted from historical solar drawings are very useful due to its strong correlation with other solar activity indices as the Group Number or the Sunspot Number (related to the solar irradiance too). Usually, sunspot areas corrected from...

    Session 5 - Solar-Terrestrial Relations, Solar Wind, Space Weather and Space Climate
    Poster

    Coronal mass ejections (CMEs) and stream interaction regions (SIRs) are different large-scale structures in the solar wind. When interacting with Earth, they may cause the most severe Space Weather effects. Between solar wind and Earth’s magnetosphere also other possible geoeffective phenomena are generated, namely “magnetosheath jets”. They are defined mainly as dynamic pressure enhancements...
