Abstract

Recently, Pi2 pulsations during the intervals of extremely quiet magnetospheric conditions (Kp = 0$\^$+/) have been reported by Sutcliffe and Lyons (2002). The authors observed several Pi2 bursts occurred simultaneously at high (magnetic latitude = 71$^{\circ}$) and low (42$^{\circ}$) latitudes during the absence of magnetospheric substorms and found that the bursts are strongly correlated with poleward boundary intensifications (PBIs), associated with enhancements of energetic ion fluxes observed by the Geotail satellite at Xgsm - -12 Re to -17 Re and Ygsm - 12 Re to 10 Re in the plasma sheet.
