Other AbstractThe data from 31 magnetometer stations at high latitude are used to examine the spatial distribution and temporal variations of auroral electrojet and of ionospheric convection during a moderate storm on May 15, 1997. Of these stations, 20 situate in between 60°N~80°N of the western hemisphere and other 11 lie along the geomagnetic longitude of about 120°E, the Europe IMAGE magnetometer chain. The results from the synthetic analyses of geomagnetic data with 1-minute resolution along latitude and longitude chains indicate that the intensity and location of the auroral electrojet center vary frequently with UT and the local time sector. The variations of the latitudinal location of the current center may result from either the northward or the southward movement of the center,or the inclination between the center and the geomagnetic latitude circle. At the same time,the longitudinal range and the positions of the twa boundaries of the ionospheric convection pattern remain basically unchanged. The relevant results are verified and complemented by results from the incoherent scatter facility EISCAT.
