AB: We report on multi-point observations of an isolated BZ disturbance detected at a wide local time sector including dayside magnetosphere in association with a tail current activation using THEMIS, Cluster, and Double Star observations around 01 UT on August 17, 2007. The unique constellation of the spacecraft allows us to examine simultaneously the propagation of the disturbance locally as well as globally. THEMIS at the late morning sector, observed an enhanced BZ disturbance that propagated tailward (and radial inward). TC1 at the dawnside detected relevant disturbance in BZ. Cluster, located post midnight sector, observed BZ enhancement accompanied with signature of field-aligned currents, in association with an enhancement of the westward electrojet observed by MIRACLE at a close local time sector. By comparing the timing of the disturbance and determining the propagation properties we discuss the possible casual relationship between the dayside disturbance and the tail current sheet activation.
