a Comparison of H-, D-, and Z-components on an NEJ day (blue curves; February 6, 1992) and a CEJ day (red curves; January 23, 1992) for PC-1 along the Indo-Russian chain of stations, showing the reduced amplitude of H-variations on the CEJ day. b Plot of equivalent current vectors on the local time latitude sector for PC-1 during the NEJ day, with the Sq focus between GUL and TKT (~35° dip latitude). c Plot of equivalent current vectors on the local time latitude sector for PC-1 during the CEJ day, showing the absence of a clear vortex
