poster XVII HAC

Due to still the on-going COVID-19 pandemic and accompanying social and economic disruptions, LOC and SOC decided to organize XVIIth HAC meeting ONLINE via Zoom platform. The program is planned for 3 hours every day from Monday to Friday (20. - 24 September 2021) 15:00 - 18:00h Croatia time (CEsT).

The Hvar Astrophysical Colloquium (HAC) is organized every two years in the town of Hvar, Croatia with aim to bring together researchers from Europe and beyond, devoted to instrumentation, fundamental as well as applied research in the field of solar and heliospheric physics, space weather and space climate.

Abstract submission deadline: 1 September 2021.

Proceedings of the XVIIth Hvar Astrophysical Colloquium - "The Sun and Heliosphere" will be published as a special issue of the Central European Astrophysical Bulletin (CEAB). The deadline for submitting your contribution is March 1, 2022. There is no page limit, recommended is up to 10 pages for posters, 15 pages for contributed talks and 20 pages for invited talks. Manuscripts should be prepared in LaTeX, using the CEAB style file. All prepared manuscripts should be sent with mail to Domagoj Ruzdjak ( Ova e-mail adresa je zaštićena od spam robota, nije vidljiva ako ste isključili JavaScript ).
