Resolution No.10 (1979): Supply of observatory magnetic data for MAGSAT project

IAGA, recognising the value of the MAGSAT geomagnetic measurements, urges the continuing support of the geomagnetic observatories and measurements at repeat stations to maintain the high precision of world magnetic charts and recommends that, until the end of 1980, observatories send hourly values (preliminary values, if need be) to the World Data Centers not later than two months after the end of the recording period.
