We used 50 Pi 2 events that were simultaneously observed at seven stations along the 210° MM during January 1995, and focused our analysis on associated magnetic energy, ((Δ<jats:italic>H</jats:italic>)²+(Δ<jats:italic>D</jats:italic>)²)/µ<jats:sub>0</jats:sub>. The times when the amplitude of the magnetic energy attained the maximum (<jats:italic>T<jats:sub>max</jats:sub></jats:italic>) were compared among these stations. We found that <jats:italic>T<jats:sub>max</jats:sub></jats:italic> has a latitudinal dependence, especially at higher latitudes, which has not been previously reported. At Kotel'nyy (L=8.50) on the poleward side of the auroral region, <jats:italic>T<jats:sub>max</jats:sub></jats:italic> occurred an average of 21 seconds earlier than <jats:italic>T<jats:sub>max</jats:sub></jats:italic> at Guam (L=1.01), and often as much as one minute earlier. The existence of latitudinal variation has implications for interpretation of issues related to timing of substorm onset; it is necessary to consider the global features of Pi 2 events in the study of auroral and magnetospheric substorms.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380567007824807680","@type":"Researcher","foaf:name":[{"@value":"T.
