Zonal asymmetry of total ozone content (TOC) in the Antarctic region is analysed using the TOMS measurements in 1979-2004. The TOC longitudinal distribution at the individual latitude circles in the latitude band 55-75° S with the 5° step is considered. From the positions of the zonal wave extremes it is revealed that the TOC zonal minimum is displaced eastward in the longitudinal sector 60° W-0° E with total shift of about 50°. The zonal maximum position is rather stable in the quadrant 90° E-180° E. Evidence is obtained that averaged geographical location of the extremes at the five latitude circles reproduces the Antarctic continent boundary in the corresponding longitudinal sectors.
