On 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. Pictures from lecture are available here. 

Winter fairytale at Hvar Observatory

Written by Jaša Čalogović Thursday, 01 March 2018 00:00

Snow at Hvar and other islands in Dalmatia is quite rare and it happens just for a short time usually once in few years. Cold weather in Europe at the end of February followed with north and cold wind Bora was the reason for snow on Hvar and other nearby islands. It is quite strange to experience Hvar in such white winter atmosphere and we publish several pictures from 27 February to illustrate that.

Mateja Dumbović obtained Marie Sklodowska-Curie fellowship

Written by Mateja Dumbovic Tuesday, 21 March 2017 14:46

In the scope of individual fellowships of the Marie Sklodowska-Curie actions within EU programme HORIZON 2020 (standard European fellowships – physics panel) project "Forbush decrease model for expanding CMEs affecting Earth and Mars (ForbMod)" by M. Dumbović was accepted for funding. The subject of the project research are depressions in the galactic cosmic ray flux during solar storms (so called Forbush decreases) and the project aim is to develop a new analytical model which would explain these phenomena and compare model results with observation at Earth and Mars. The project will utilize a number of ground-based as well as spacecraft measurements including the Curiosity rover at Mars. M. Dumbović will implement this two-tear project at the University of Graz under supervision of Dr. Manuela Temmer and in collaboration with Dr. Christian Möstl from the Space Research Institute in Graz and Dr. Bernd Heber and Dr. Jingnan Guo from the Christian-Albrechts University in Kiel. A short overview of the evaluation results (Flash Call Information) is available at the EU participant portal.

On November 17, 2016 Dr. Bojan Vršnak participated in the Croatian scientific TV show (HRT-3: "Third Element") entitled "Solar System". In the show, he explained the formation and evolution of the Sun, effects of the solar wind and the solar eruptive processes on the Earth and other objects in the solar system. Various solar-activity effects on the robotic and crewed space missions, including the future missions to Mars, were discussed. 

Video of TV show "Third element" on 17.11.2016 is available here (only in Croatian)
