Results of Rocket Observation of Electron Density at Syowa Station

The twelfth and thirteenth Japanese Antarctic Research Expeditions (JARE) carried out firings of two S-160JA rockets and twelve S-210JA pockets to observe the polar ionosphere and auroral phenomena at Syowa Station (69°00' S, 39°35' E; geomagnetic lat. 69.6°S, long. 77.1°E) in Antarctica. The electron density profiles of the ionosphere obtained by the two S-160JA rockets and eight S-210JA rockets experiments are given in this preliminary report
