M. Dumbović (project team member) and B. Vršnak (project mentor) attended second workshop „Large‐Amplitude Oscillations in Solar Prominences“ (9.-13.11.2015) 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. 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.

From 5th to 9th November 2015, Jaša Čalogović attended 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 poster "Photosphere and Chromosphere Telescope at Hvar Observatory" was presented, showing solar observations from Hvar in white light and H-alpha.
