Abstract
Digital ionosonde and magnetometer observations from a polar cap station are used to estimate the fraction of Region 1 current that flows across the polar cap. For a winter case study using data for 2001 Feb 18 the cross-cap current was 3.9Â ÃÂ 104Â A Pedersen current and 6Â ÃÂ 104Â A Hall current. This total current is only a small percentage, â¼5%, of the Region 1 current.
