The transits of Mercury across the solar disk are rare phenomena, although Mercury orbits the Sun in just 88 days. The reason for this is that Mercury orbits the Sun with the certain angle to the ecliptic, ie. the plane that the Earth orbits the Sun. Mercury transit in Croatia was visible on 9 May 2016, started at 13:12h local time and could be seen for almost 7 hours. Unfortunately, end of transit was not visible from our region because the sunset was at 20:10h and end of transit was at 20:42h. This rare phenomena was possible to observe from Hvar, and it was recoreded in white light and H-alpha using Hvar solar telescope. The next transit of Mercury will be visible from the Croatia in 2019.

From 21 to 23 April 2016
Festival of Science was organized at city hall in the town of Hvar, and this year's festival theme was "
Science and Art". The event was organized by the Observatory Hvar and the Elementary School of Hvar, Stari Grad, Jelsa and the Archaeological Museum in Zagreb.
Science Festival is being held for the 14th consecutive year in Croatia and its goal is to bring the science to pupils of primary and secondary schools and the entire interested general public. This year, the Science Festival was organized in 18 cities in Croatia, and it was the second time that city of Hvar hosted it. Compared to the last year, organizers offered a much
richer program and the Festival in Hvar lasted for three days, that was visited by students of almost all schools on the island (elementary school of Hvar, Stari Grad and Jelsa).

Festival of Science with special topic "
the Sun" was held for the first time in the Hvar town loggia on 20th April 2015, organized by Primary school Hvar and Hvar Observatory. The aim of festival is promote and raise awareness of science, technology and the environment with the aim of getting children interested in science and technology. The program consisted of the exhibition of student's artwork, a workshop "Funny quiz about the Sun" with more than 40 participants and a lecture "Why and how do we study our nearest star – the Sun?". A promotional/educational stand was set, where information was presented about Hvar Observatory, the Sun and the International Astronomical Union initiatives. Additional educational interactive stand was also set, where prism experiment was performed and that offered several puzzles of the Sun in different colors. During the day the visitors – students, teachers and parents were observing the Sun through the telescope where several sunspots were visible, while in the evening observations of the Moon, Venus, Jupiter and Orion nebula were organized with amateur telescopes.
During the Festival of Science, from 20. to 25. April 2015, staff members of Hvar Observatory gave also two public lectures in Astronomy Center of Rijeka (23.4.) and organized workshop (24.4.) and lecture (25.4.) in Technical museum, Zagreb.

New space weather forecast tool „
Forbush decrease Forecast Tool (FDFT)" is now available at
Hvar Observatory webpage. FDFT is based on an empirical probabilistic model for the estimation of the Forbush decrease magnitude based on the remote CME/flare observations. It uses CME-speed, CME width, associated flare source position, associated flare soft X-ray peak intensity, and interaction parameter (likeliness of the CME-CME interaction) as an input. It provides Forbush decrease (FD) magnitude probability distribution and expected FD magnitude interval as an output. The details regarding the forecast method and the evaluation will be described in detail in the manuscript "Forbush decrease prediction based on the remote solar observations" by Dumbović et al., which is in preparation.

Nikša Novak, technician at Hvar Observatory was retired at the begining of this year, after 36 years of employment at Hvar Observatory. Nikša was irreplacable in keeping the Hvar Observatory running smoothly, but also one of the most diligent observers with double solar telescope. Therefore, his colleagues organized a farewell party for him on 28.01.2015. at the Observatory and awarded him a convenient farewell present - a woodcut of Nikša observing with the double solar telescope in the early days of his employment.
