Monthly averaged hourly values and SI. (a) Monthly averaged hourly values of H component variation of the earth's magnetic field for November 2011, showing the time shift in local time-dependent ionospheric diurnal variation and greater peak amplitudes at equatorial sites, CBY (approximately 110 nT) and VEN (approximately 80 nT), compared to that at low-latitude stations: PBR (60 nT) and HYB (50 nT). (b) SI at 21:50 UT during a strong geomagnetic storm on 28 November 2011, a time-independent event recorded simultaneously at all stations.
