Fig. 3From: A case study of correspondence between Pc1 activity and ionospheric irregularities at polar latitudesThe Pc1 pulsation power (left, upper panel) and the ROT time series from different satellites over MZS (left, bottom panel) on 22 February 2007. On the right corresponding ionospheric pierce points of satellites are plotted between 65°–80°S and 120°–200°E geographic coordinates; CGM meridians and parallels are shown as dotted lines; filled circles mark the start times; pink star represents MZSBack to article page
