Magnetospheric ULF wave phenomena stimulated by SSC

Several ssc were recorded simultaneously at the low-latitude longitudinal and along the 210 degrees magnetic meridian networks. The considered ULF wave phenomena stimulated by the ssc comprise main and preliminary impulses, Psc 3 pulsations, ssc-related Pc 3 and cavity-like oscillations. The analysis of observed ssc shows that the preliminary impulse is still not able to explain invoking by the existing theory. It is also found some problems concerning the interpretation of features of other ssc-associated wave phenomena. Further specially coordinated observations at a world-wide magnetometer network with high precision of time synchronization are required to understand these unresolved problems.
