PC (type of index: Polar Cap index horizontal component disturbances; time resolution: 1-minute UT interval, North PCN from 1975 and South PCS from 1995 onwards; unit: mV/m) is deduced from the deviations in the horizontal H and D magnetic field components from the quiet level at two polar cap stations (Thule and Vostok for respectively the PCN and PCS). PC aims at monitor 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. PCN is determined by the National Space Institute, Technical University of Denmark (DTU), Denmark; PCS is determined by the Arctic and Antarctic Research Institute (AARI), Russian Federation. PC time series is formally recognised and endorsed since 2013 by International Association of Geomagnetism and Aeronomy (IAGA).
