IDS3Geo Dubrovnik 2018 group photoFrom 8th to 11th May 2018, 2nd international doctoral seminar on geodesy, geoinformatics and geospace (IDS3GEO) was held in Dubrovnik, organized by the Faculty of Geodesy, University of Zagreb. IDS3GEO hosted numerous sessions related to astrophysics where our collaborators such as Prof. Arnold Hanslmeier (Graz University) and Prof. Bernd Heber (Kiel University) gave lectures. In different sessions, Bojan Vršnak ("Reflection of Cosmic Rays at Oblique MHD Shocks"), Jaša Čalogović ("Probabilistic model for heliospheric propagation of CMEs: DBEMv2 web application") and Mateja Dumbović ("Forbush decrease model for expanding CMEs - ForbMod") also presented their work.

thumb ISSI meeting 2018From April 8 to 13, 2018 Bojan Vršnak attended the International Team Meeting of the team Manuel Luna: "Large-Amplitude Oscillations as a Probe of Quiescent and Erupting Solar Prominences", held at the International Space Science Institute (ISSI) in Bern, Switzerland. Bojan Vršnak tasks were related to the oscillations of prominence-carrying magnetic flux ropes, implications for the stability and loss of equilibrium. He also gave a talk on physical background of prominence oscillations entitled "Coronal and Prominence Diagnostics based on Prominence Oscillations".

thumb HPD Vrsnak2018On March 22, 2018, Bojan Vršnak gave a public lecture on the physical background of eruptive processes on the Sun. The lecture held at the public library "Bogdan Ogrizović" was organized by Croatian Natural Society (Hrvatsko prirodoslovno društvo, HPD). In the lecture entitled "Solar Eruptive Activity" (Sunčeva eruptivna aktivnost), he presented basic mechanisms that cause various forms of solar eruptions, their space-weather consequences and effects in geospace.
