Research Abstract

Two all-sky airglow/aurora imagers were installed at two Canadian stations at Resolute Bay(RSB)and Athabasca observed polar-cap plasma patches almost always(ATH))in 2005, At RSB, we always during southward IMF periods, From two-dimensional cross-correlation analyses, we determined velocity vectors of the patches, which indicates the ionospheric convection vector, that showed high correlation with the IMF-By and -Bz variations. At ATH, we often observed isolated proton arcs and Stable Auroral Red (SAR) arcs, which were located equatorward of the amoral oval The appearance of the isolated proton arcs was highly correlated with the Pc 1 geomagnetic pulsations measured simultaneously at ATH, suggesting interactions between the electromagnetic ion cyclotron (EMK) waves and protons in the vicinity of the plasmapause and the ring current. Similar interactions without waves were also suggested for the SAR arcs, which appeared after the substorm expansion phase even without geomagnetic storm. These observations show promising capability monitor magnetospheric processes from the ground stations, whit would contribute to the future satellite projects such as THEMES, ERG, and Scope/Xscale
