The International Association of Geomagnetism and Aeronomy (IAGA)
Recognising

  • The outstanding importance of the SC (sudden commencement) and SFE (solar flare effect) data in geomagnetic, ionospheric, space weather, and space climate research

Noting

  • That in accordance with IAGA Resolution No. 6 at the XVI IUGG General Assembly (1975), and Resolution No. 8 at the 8 th IAGA Scientific Assembly (1997), the institute of ”Ebro Observatory” is responsible for the collection and preparation of the SC and SFE lists as part of its Rapid Magnetic Variation Service

Expresses

  • Deep appreciation for the work performed to date by Ebro Observatory, and

Urges
