Dear Colleagues,

We hope that you are all safe and well in your homelands. The SOC is monitoring the governmental and institutional recommendations related to COVID-19 outbreak. Since the health and safety of our participants is our main priority, SOC and LOC have decided to hold the conference later this year, after the normalization of situation. The programme remains as planned, in terms of structure and content, and already paid conference fees will remain valid, of course. Further updates about 12th SBAC will follow as soon as we receive the confirming information that scientific conferences are allowed to be held.

Hopefully, this inconvenience will not influence too much your plans and life. We wish you good health and many published papers.

Looking forward to seeing you at 12th SBAC.




The aim of this series of conferences is to contribute to the developing of collaboration and friendship of Serbian and Bulgarian astronomers, to stimulate the exchange of experiances, joint projects and common research. We organized eleven Serbian-Bulgarian and Bulgarian-Serbian astronomical conferences and this, XII SBAC will be held in Soko Banja.

When this series of conferences started the connections between Bulgarian and Serbian astronomers were rare, mutual visits sporadic and joint project do not existed. Now, after 22 years from the first one, as the result of these conferences we have five mutual SANU - BAN projects and new ones are in preparation; we have joint observations and we know much better each other. We hope that this conference will be also very useful for the further development of mutual collaboration, planning of common investigations and fruitful scientific research.
