Propagation characteristics of low-latitude Pc3 pulsations in east-west direction

An east-west chain of three stations was established in north china near geomagnetic latitude 29.6 degrees (L = 1.3) within a geomagnetic longitude span of 40.2 degrees from Oct. 10 to Nov. 29 in 1996. Propagation and polarization characteristics of Low-latitude Pc3 pulsations were studied. It is concluded that the westward propagation of Pc3 pulsations is dominant in the morning and the eastward propagation is dominant in the afternoon. NW-SE of major axis azimuth and right-handed polarization are dominant in the daytime.
