    Abstract
  • An interplanetary shock event on 14 July 2012 is studied using observations with Super Dual Aurora Radar Network (SuperDARN), northern hemispheric IMAGE magnetometer chain and All-sky Aurora Imagers at Zhongshan station, Antarctica. At 18:10UT, an interplanetary shock struck the magnetosphere and induced geomagnetic sudden commencement. Observations of SuperDARN present that the ionosphere convection of northern hemisphere was enhanced obviously. The Hankasalmi radar, whose field of view covers the Yellow River station, found that the ionospheric F layer was severely disturbed, e.g. the echoes number increased obviously and inversion phenomenon of local ionospheric convection speed emerged from 18:10UT to 18:33UT. There are three irregularities in F layer measured by Hankasalmi radar and their speeds in line-of-sight reached 600m·s-1 after 18:33UT. Kerguelen radar around Zhongshan, conjugating with the Yellow River station, observed that the number of the echoes had little change and the echoes are mainly from E layer and there are almost no echoes from F layer. However, the All-sky Imagers at Zhongshan station observed the enhancement of aurora activity. The observation difference of northern and southern hemispheres nightside ionospheric responses are mainly because of that they were at polar night and polar day respectively.
