From 5. to 19. February 2016 Jaša Čalogović visited Dr. Benjamin Laken at the Department of Geophysics, University of Oslo. The aim was to work on current research topics (eg. regional influences of cosmic rays on certain types of clouds), develop future research plans and strengthen the collaboration. During the stay J. Čalogović also gave a talk "A critical look at cosmic ray-cloud relationships" at Department of Geophysics. 

24th European Research Course on Atmospheres (ERCA) was organized from 6. January to 4. February 2016. by Universite Joseph Fourier and CNRS in Grenoble, France. ERCA is a high level international course on the Physics and Chemistry of atmospheres, the climate system and climate change, atmospheric pollution at different scales and the human dimensions of environmental changes. The course also covers the solar influences on Earth's atmosphere and climate. More than 35 students from all around the world participated ERCA.
Jaša Čalogović was invited to give students two lectures ("A cosmic ray - cloud link and cloud observations" and "Composite analysis and Monte Carlo methods - an example with Forbush decreases and cloud cover"). Aim of lectures was to show effects of space weather on Earth, present cosmic - ray hypothesis and show potential problems that were present in past studies analyzing geophysical data.

1-5. February 2016 M. Dumbović visited the Udaipur Solar Observatory (USO) of the Physical Research Laboratory (PRL) under the Department of Space in India. Several meetings were held with Dr. Nandita Srivastava regarding the future collaboration on Space Weather research, and the USO staff members presented and described the USO scientific instruments. M. Dumbović held a seminar titled “Space Weather research at the Hvar Observatory” for the staff members and students.

          

International conference Science for Space Weather was held in Goa, India 24-29 January 2016. The conference was accompanied by a Space Weather school for graduate and PhD students funded by CAU, CESSI, COSPAR, ILWS, SCOSTEP-VarSITI, PRL, and ISRO. More than a hundred scientists and students attended the conference from 21 different countries, among them T. Žic and M. Dumbović from Hvar Observatory with two contributions “The Hvar Observatory CME-Effectiveness Forecast Tools” and “The drag-based model application".

M. Dumbović and B. Vršnak attended second workshop „Large‐Amplitude Oscillations in Solar Prominences“as members of the International Space Science Institute (ISSI) team led by Manuel Luna Bennasar, which includes also scientists from Spain, UK, USA, China and Belgium. B. Vršnak presented new results on the physical nature of the solar prominence oscillations excited by coronal large amplitude waves, obtained in collaboration with T. Žic in the frame of SOLSTEL research program (pdf). M. Dumbović, invited as a young scientist, presented the catalog of observed large-amplitude oscillations compiled based on extensive number of publications in recent years, in collaboration with J. Čalogović (pptx).

From 5th to 9th November 2015, Bojan Vršnak attended as a member of SOC a conference "Coimbra Solar Physics Meeting: Ground-based Solar Observations in the Space Instrumentation Era" held in Coimbra, Portugal. The main topic of the meeting was the state-of-art of solar ground-based and space-based observing techniques and related topics. During the conference two posters were presented: "Forecasting the arrival of Coronal Mass Ejections: The Drag-Based Model" (Vršnak B., Žic T., Čalogović J., Dumbović M.) and "Photosphere and Chromosphere Telescope at Hvar Observatory" (Čalogović J., Dumbović M., Vršnak B., Brajša R.).

On September 29, 2015, Bojan Vršnak presented a talk entitled „What the Sunlight Reveals to us" at a symposium "Man and the Light" held at Croatian Academy of Sciences and Arts. Symposium was organized by the Croatian Physical Society in the frame of the International Year of Light 2015. The recording of lecture is available here.

From 20 to 25 September 2015, Bojan Vršnak attended a conference „Multi-Wavelength Studies of the Solar Atmosphere" organized by the SOLSTEL, Grece, where he presented an invited-review on the physical nature of the solar coronal large amplitude waves, including the results obtained in the frame of the SOLSTEL research program.

Free interactive exhibition "European Space Expo" was held on main square in Zagreb (Trg bana Josipa Jelačića) from 12 to 21 June 2015. Exhibition presented the services and applications of the major European space programs in the domain of satellite navigation (Galileo) and Earth Observation (Copernicus). The main objective of Space Expo organized by European Commission was to inform the public about the positive effects of European space programs on the daily lives of Europeans. Thanks to rich and interactive audio-visual materials, visitors could discover the various applications of satellite technology. During the whole exhibition period Space Expo visited more than 83.000 people. Faculty of Geodesy was one of the main local partners that also organized various public lectures. One of the lectures was held by Dr. sc Roman Brajša, head of Hvar Observatory about research performed at Hvar Observatory ("Istraživanje svemira na Opservatoriju Hvar"). General presentation about Hvar Observatory was also available at local interactive kiosk during the whole exhibition period and was prepared by Dr. sc Jaša Čalogović.

A workshop was held at the Hvar Observatory from 26 to 29 May 2015 with general topics on the cosmic ray modulation, Forbush decreases, coronal mass ejection initiation and propagation, and magnetic clouds in the interplanetary space. There were 14 participants from the Physics department of the University of Kiel, Physics Institute of the University of Graz, Space Research Institute in Graz and Hvar Observatory.
