<name>PCN (Polar Cap North) index</name>
<description>Measure of the geomagnetic activity over the polar caps caused by changes in the interplanetary magnetic field (IMF) and solar wind, driven by the geoeffective interplanetary electric field irrespective of time, season and solar cycle phase. Proxy for the solar wind merging electric field.
