Sun and Geosphere is a peer-reviewed international journal published by the Balkan, Black Sea and Caspian Sea Regional Network on Space Weather Studies (BBC SWS Regional Network).

The BBC SWS Regional Network was founded in June 2005 by decision of the "IHY Regional planning meeting for the Balkan and Black Sea region", Sozopol, Bulgaria,6–8 June 2005 (see Protocol). In this Protocol as item 3 (below the Memorandum of Understanding) reads:
"The Regional Network will publish an International referred Scientific Journal Sun and Geosphere with international editorial board"


The first issue of the magazine was printed in early 2006 in Baku Azarbeydzhan.

Editorial Policy


Sun and Geosphere is issued twice a year. The journal is open to original contributions in solar and solar-terrestrial physics. The submitted contributions can be accepted only if they were neither published before nor destined to another publication. The Sun and Geosphere journal is also open to publish in special issues the scientific results of some meetings with subjects in the above-mentioned fields. All the manuscripts submitted to both regular and special issues are reviewed by competent anonymous international referees.

Only peer-reviewed papers are published in Sun and Geosphere.
