Range-time plots of a northward component of line-of-site plasma velocity, b 15-min high-pass filtered plasma velocity, c and d detrended TEC and normalized temperature deviation (d3) at the magnetic conjugate points of the beam-08 direction in the Southern Hemisphere, e and f two-dimensional maps of d3 in geographic coordinates. The two red curves with the yellow markers every 10 range gates indicate the locations of line-of-site of beam-08 of the SuperDARN Hokkaido east radar and their magnetic conjugate points in the Southern Hemisphere. The five orange points on these curves indicate the number of range gate from 0 to 40. The two triangles above the left panel correspond to the time of two-dimensional maps of d3. The blue and purple curves in panels (e) and (f) indicate the sunset terminators at a height of 105 and 300 km, respectively
