... Compressional Pc 5 ( ULF ) waves, found on the nightside close to the flanks of the magnetosphere , are the dominant pulsations occurring beyond L =8. ... Accordingly, the events are strongly associated with high beta plasma clouds and are much more likely to be observed near the equator than >10њ off the equator (see, e.g., Anderson, 1993). ... Azimuthally polarized toroidal Pc 5 pulsations are thought to be fundamental mode toroidal field line resonances (FLR) with magnetic node at the equator. ...
