Abstract: It is briefly described of coherent scattering radar SABRE and its working principle in observing Pc5 geomagnetic pulsations.The statistical analysis shows that the occurrence of poleward propagating events peaks near local midnight whereas for equatorward events the occurrence peaks at about 18:00 LT.The statistical results are presented here of the diurnal variation of occurrence frequency,the correlation with geomagnetic activity and the relationship with the background plasma convection pattern for above two types of pulsation events.
