50 years after the International Geophysical Year (IGY) in 1957 -1958, one of the most successful international science programs of all time, the "International Heliophysical Year" (IHY) was organized in 2007 -2008. The term "Heliophysical" emphasized studyi ng the interconnectedness of the entire solar -heliospheric -planetary system, thus broadening of the concept of "geophysical," extending the connections from the Earth to the Sun and interplanetary space. The IHY had the following science goals for 2007 -2008: - Develop the basic science of heliophysics through cross -disciplinary studies of universal processes. - Determine the response of terrestrial and planetary magnetospheres and atmospheres to external drivers. - Promote research on the Sun -heliosphere system outward to the local interstellar medium – the new frontier. - Foster international scientific cooperation in the study of heliophysical phenomena now and in the future - Communicate unique IHY results to the scientific community and the general public. To coordinate the IHY -related activities, several regional networks were organized. Only one of them is still active: the Balkan, Black Sea, and Caspian Sea Regional Network (known as the “BBC Network”) for Space Weather Studies which was created in 2005 a nd earlier this year it celebrated its 20th anniversary. In this presentation I will highlight the history, activity, and opportunities for joint research.
