Resolution No.15 (1979): Keeping standard of K-index scaling

IAGA, noting that standards of K-index scaling can change, urges that each country appoint a qualified scientist to check regularly the K-index scalings at all the observatories within that country to maintain these standards and requests that Observatory Directors notify the Central Km-Bureau (Institut de Physique du Globe, Paris) of any changes of the Chief Observer at the Km Observatories to allow the Central Km-Bureau to be alert to detect possible systematic changes in K-scaling.
