New paper published in Nature Communications

An international team of scientists led by Dr.sc. Christian Möstl from the Space Research Institute (Institut für Weltraumforschung, IWF) in Graz, including couple of Hvar Observatory team members, recently published a scientific paper in Nature Communications. The paper Möstl et al. regards the non-radial propagation of CMEs, using a synthesis of data of a fast CME from seven different space missions. CME, which originated in an active region near the disk centre, was forecasted to have a significant geomagnetic impact. However, the CME is demonstrated to be channeled during eruption into a direction away from its source region, leading only to minimal geomagnetic effects. In situ observations near Earth and Mars confirm the channeled CME motion, and are consistent with an ellipse shape of the CME-driven shock provided by the new Ellipse Evolution model, presented in the paper. The results enhance our understanding of CME propagation and shape, which can substantially influence the geomagnetic effects of CMEs. The publication of the paper was covered by several media such as space.com(ENG), the Conversation(ENG), Discovery News(ENG), Sueddeutsche Zeitung(GER), Der Standard(AUT), tportal(CRO).

Written by Mateja Dumbović on . Posted in News

FZ2015-SunceHvar Observatory participated in the 13th Festival of Science, with special topic "the Sun" which was held across Republic of Croatia 20-25. April 2015. The aim of festival is to promote and raise awareness of science, technology and the environment with the aim of getting children interested in science and technology. This year Hvar Observatory together with Hvar local elementary school organized for the first time Festival of Science in Hvar. In addition, a public lecture was held in Rijeka and a workshop for children, as well as a public lecture, was given in the Technical museum in Zagreb.

thumb UniFair2014-GEOFFrom 14. to 15. November 2014 University of Zagreb organized University Fair held in Student Centre in Zagreb. The Fair aims to inform prospective students about courses of study, the faculties achievements in fields of science and technical equipment, programmes of study, career opportunities, and many other interesting details. Faculty of Geodesy was also one of fair participants where part of its exhibition space was devoted to Hvar Observatory. Our instruments, work and projects (including SOLSTEL) were presented in "Solar and stellar research on Hvar Observatory" presentation as well as by brochure and a poster about Hvar Solar Telescope. Efforts of Faculty of Geodesy were recognized by organizers and Faculty of Geodesy was titled as the best institution in category of most comprehensive information about study programme.
