Beside the recent coronavirus pandemic issues and restrictions that were introduced also in Croatia by the mid of March, on 22nd March 2020 at 6:25 AM Zagreb was hit by powerful 5.5 magnitude earthquake with epicentre close to Zagreb city centre. This was the strongest earthquake in Zagreb in the last 140 years and caused severe damage in historical city centre. The Faculty of Geodesy building where Hvar Observatory offices are situated was also impacted. Few pictures after the Zagreb earthquake are available here.Read more: Hvar Observatory also hit by earthquake in Zagreb

Following the success of the first meeting held in China (CESPM 2017, Kunming, Yunnan) the 2nd China-Europe Solar Physics Meeting (CESPM 2019) was organized from 6 to 10 May 2019 in Hvar, Croatia. Main aim of this meeting is to strengthen the collaboration between European and Chinese scientists, in particular among young scientists. The scientific sessions were included the following topics: 1) Solar Interior, Dynamo and the Solar Cycle; 2) Heating and Coupling of the Solar Atmosphere layers; 3) Fundamental Plasma Processes: Magnetic Reconnection, Waves, Emission, Particle Acceleration; 4) Manifestations and Triggering of Solar Flares and Coronal Mass Ejections; 5) Solar-Terrestrial Relations, Solar Wind, Space Weather and Space Climate.CESPM 2019 photo gallery and uploaded presentations are now also on-line.

Austro-Croatian Workshop at Zagreb Observatory
Written by Jaša Čalogović Sunday, 16 December 2018 12:34
From 06 to 08 December 2018 a three-day „Austrian-Croatian scientific workshop: Solar and Heliospheric Physics“ was held at Zagreb Observatory. The workshop was organised in the scope of the austrian-croatian bilateral project “Development of the Drag-Based-Ensemble Model for studies on the propagation of solar storms (DBEM)” between Hvar Observatory, Faculty of Geodesy, University of Zagreb and Institute of Physics, University of Graz and was supported by Croatian Astronomical Society. The workshop had 26 scientists and students from the University of Graz, Hvar Observatory, Faculty of Science - University of Zagreb, Skolkovo Institute for science and technology and Zagreb Observatory. A number of different topics related to solar and heliospheric physics were presented, discussed and developed further through hands-on activities. The workshop was concluded with arrangements for future collaboration and planning of a next-in-line workshop in Graz 2019.Workshop programme

Hvar Observatory almost destroyed in a forest fire
Written by Jaša Čalogović Wednesday, 12 September 2018 12:31
A forest fire broke out at a distance of 500 meters from the Hvar Observatory on Tuesday, September 11, 2018, at about 4:30 pm. Since the very strong wind was blowing in the direction of the Observatory, the fire spreaded quickly to the telescope domes and Napoleon fortress. The dome of Austrian-Croatian telescope was saved from fire that approached less than few meters from the building thanks to the great efforts of 40 firefighters from Hvar, Stari Grad and Jelsa. The fire was localized around 6 pm with the help of 3 firefighting planes. Luckily, the bigger damages were avoided and the fire didn’t damage any object of the Observatory Hvar, but in total about 5 ha of low vegetation were burnt down. Pictures and video of the fire near Observatory are available below.Read more: Hvar Observatory almost destroyed in a forest fire
Total Moon eclipse at Hvar Observatory
Written by Jaša Čalogović Sunday, 29 July 2018 12:05
On 27th July 2018 the total Moon eclipse was also visible from Hvar Observatory. This time the eclipse was one of the longest (almost 2 hours) and very dark since the Moon was passing directly through the middle of the Earth’s shadow. It started at 20:30 h with a maximum at 22:22 h and ended at 23:13 h. About 30 local people and children from Hvar gathered at Hvar Observatory and enjoyed the show on the sky. Mars was also visible near the Moon and it was very bright due to the closest position to the Earth (opposition) in last 15 years. Beside the Moon and Mars on the evening sky were also visible Jupiter and Saturn. All visitors had a chance to look all these objects trough the portable 10-inch telescope.
First results from ALMA published in Astronomy & Astrophysics
Written by Jaša Čalogović Thursday, 31 May 2018 11:45
On 23rd May, Astronomy & Astrophysics published Brajša et al. paper “First analysis of solar structures in 1.21 mm full-disc ALMA image of the Sun” on the cover page where the first results using the ALMA (Atacama Large Millimeter/submillimeter Array) for solar observations were presented. The aim of the paper was to identify different structures and their intensities in the solar atmosphere in full-disc solar ALMA images. ALMA is currently the largest radio telescope in the world and it is composed of 66 high-precision antennas, which operate on wavelengths of 0.32 to 3.6 mm.
Lecture about meteorology in Hvar elementary school
Written by Jaša Čalogović Thursday, 26 April 2018 13:41
On 24th April, dr. sc. Jaša Čalogović gave a lecture about the meteorology (“Meteorologija – kako prognozirati kakvo će vrijeme biti u Hvaru?”) in the Hvar elementary school. After the lecture the pupils were divided in several groups and a small quiz related to meteorology was organized. Beside the questions, pupils became the synoptic map of the Europe with aim to make alone the weather forecast for Hvar. The symbolic prizes (sweets and chocolate) were given to the best teams that obtained the highest number of points in quiz.
ISSI workshop in Bern
Written by Jaša Čalogović Monday, 16 April 2018 23:45
From 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".
