内容記述 | Polarization and direction of arrival of VLF emissions have been observed at Syowa Station in the Antarctic by a combination of a vertical antenna and a crossed loop antenna with their planes oriented in geomagnetic E-W and N-S directions. The results obtained with a polarimeter show that the emissions at 750Hz, 12kHz and 25kHz were roughly left-hand polarization waves (whistler mode) in all seasons, when one viewed towards the observation site on the earth's magnetic field. But there seemed to be some seasonal variations in the ratio of right-hand polarization waves to left-hand ones. A pronounced example is that the emission at 25kHz was linearly polarized in winter (July and August). The oscillographic patterns obtained with a direction finder seem to indicate that the emission at 12kHz arrived simultaneously from various directions, and that the emission was almost elliptically polarized. But in a few cases, the emission seemed to come down roughly from a vertical direction along a geomagnetic field line, and to be circularly polarized. | |||||
