The paper focuses on ionospheric signatures of lobe reconnection near magnetic noon under steady northward IMF. Enhanced Type 2 aurora observed by a meridian scanning photometer and reverse ion energy dispersion measured during a DMSP satellite pass provide evidence for the reconnection. Tomographic imaging of the spatial plasma distribution reveals key footprints of the processes, including the location of the adiaroic boundary separating the lobe cells from the closed LLBL precipitation, the dispersion of precipitating soft ions along sunward convecting field lines, and the possible presence of a Birkeland current sheet at the adiaroic boundary. The chain of ionospheric tomography receivers from Troms¿ to Svalbard provides a powerful tool for investigation of the ionospheric response to magnetospheric boundary layer processes and their coupling to the ionosphere. ¿ 1999 American Geophysical Union |
