womens day solar stormScientists from Hvar Observatory (Croatia), the University of Graz (Austria), and Skoltech (Russia) along with their colleagues from the U.S., Belgium, and China have investigated a peculiar solar storm that happened on the International Women’s Day 2019. The all-female research team unraveled how a double structure erupted from the Sun, resulting in a plethora of phenomena observed across the electromagnetic spectrum, eventually merging into a single structure that sped toward the Earth. Published in Astronomy & Astrophysics, the study contributes to accurate predictions of hostile space weather events.

thumb mateja chizhevsky medal 2021After EGU and SCOSTEP awards for distinguished young scientist Dr. Mateja Dumbović received another confirmation of exceptional contribution in the field of Space Weather – The Alexander Chizhevsky Medal for Space Weather and Space Climate. The prize rewards a young researcher (younger than 35 years, or having successfully defended her/his thesis within the last 6 years prior to the ESWW2020, i.e. after October 30th, 2014) for outstanding achievements in space weather with an innovative approach.
This award is given every year since 2014 to the best scientists by the European Space Agency, the Belgian Solar-Terrestrial Center of Excellence and the Space Weather Working Team, in collaboration with the scientific magazine Journal of Space Weather and Space Climate. Award ceremony was held online on 2.3.2021, opened by prof. Jean Lilensten, the chair of medal committee. Among friends and family, Croatian minister of Science and Education Dr. Radovan Fuchs dean of Faculty of Geodesy prof. Almin Đapo, head of Hvar Observatory Dr. Roman Brajša, representatives from Russian and Norwegian Academy of Sciences, as well as representatives from Croatian Agency for Science and Higher education attended the ceremony.

thumb Bojan Vrsnak most cited 2021Great news are coming from Standford University (California) where John Ioannidis and his associates recently released study that identified the top 2% of the world’s working scientists in regard to scientific citation. Among the around 160 000 most cited researchers worldwide in all scientific disciplines there are 47 scientists from Croatia (list is available here), 23 of them from University of Zagreb and, no more no less, our colleague Dr. Bojan Vršnak is also one of them.
The list of top 2% scientist worldwide was generated using Scopus database for period from 1996 to 2019 based on citations, h-index, co-authorship-adjusted hm-index, citations to papers in different authorship positions and a composite indicator. A list of the most impacting scientists in 2019. was published in the study as well.

thumb Neowise comet 07 2020NEOWISE comet (C/2020 F3) is currently one of the most spectacular objects on the night sky. It was discovered on 27th March 2020 by NEOWISE space telescope and it reached its perihelion (closest point to the Sun, 0.29 AU) on 3rd July. Its closest approach to the Earth will be on 23rd July at a distance of 0.69 AU. Ivica Skokic from Hvar Observatory made a beautiful photo of a comet NEOWISE from small town Samobor near Zagreb on 10th July which we publish here.
