As society becomes increasingly dependent on space-based systems, it is vital to understand how space weather, caused by solar variability, could affect, among other things, space systems and human space flight, electric power transmission, high-frequency radiocommunications, global navigation satellite system (GNSS) signals, as well as the well-being of passengers in high altitude aircraft.

Severe magnetic storms resulting from coronal mass ejections are causes of failures of many geostationary orbit communication satellites, radio blackouts and power outages on Earth. The ability to predict space weather accurately could assist in preventing or minimizing impacts of severe magnetic storms on space-based services and systems and on ground power systems.

International cooperation in research and development activities in the field of solar-terrestrial physics is important to all nations, in particular developing nations, owing to the high cost of such activities and the increasing involvement of all nations in the use of outer space for peaceful purposes.

The International Space Weather Initiative (ISWI) is a programme of international cooperation to advance space weather science by a combination of instrument deployment, analysis of space weather data from these instruments in conjunction with other data and communication of such results.

ISWI Newsletter

The ISWI Newsletter is maintained by the International Center for Space Weather Science and Education of Kyushu University (ICSWSE).

All back issues of the ISWI Newsletter are archived at the aforementioned ISWI Website (of Sofia, Bulgaria). The newsletter started in 2009 and over 100 issues come out annually. Material for publication (anything related to space weather) is always welcomed by the editor of the ISWI Newsletter.
