In order to investigate relations between low-latitude Pi 1-2 pulsations on the ground and substorm-associated variations in space, we analyzed magnetic data from the conjugate area of L=1.3-2.1 and λ~140°E, and from AMPTE/CCE in the midnight sector during August 9 to September 4,1986. From the correlation analysis, most of low-latitude Pi pulsations are found to occur within +1 to -2 min of the onsets of substorm-associated dipolarizations at geocentric distances of 8-9 R_E in the magnetotail. The dipolarizations appear to be localized in the magnetotail, because the orbiting spacecraft often cannot detect a dipolarization corresponding to an obvious Pi 2 on the grouud.
