Worldwide geomagnetic data, GIC indices and alert: INTERMAGNET observatories
============================================================================

.. contents:: Table of contents

As specified for product INTmag, data from INTERMAGNET observatories will be used only for the limited number of events that will be selected, so that a manual selection of the observatories and of the time period will be made. For the selected observatories GIC index (specifically GICx and GICy) will be calculated.
