 note = {P(論文), An array of four low latitude induction coil magnetometer stations has been used to study Pc 3 interstation phase variations and polarization characteristics over a longitudinal range of 17°at L=1.8 and a latitudinal range of 10°from L=1.8 to 2.7. Five days of data recorded between March 25-30,1982 have been analysed. The east-west chain shows generally highest coherency between north-south field components with relatively small interstation phase differences corresponding to low azimuthal wave numbers in the range |m_<x, y>|&lsim;6. The northsouth stations show greatest coherency between the east-west field components and slightly higher wave numbers. Azimuthal wave propagation is towards the west in the morning and is associated with left-hand polarization. In the afternoon propagation is eastwards and the waves are right-hand polarized. Propagation in the latitudinal direction is always towards the south, away from the equator. These results are interpreted in relationship to wave source models and it is concluded that they are consistent with generation by field line resonances situated at L>3.},
