  The Cluster spacecraft experienced several boundary layer encounters when flying outbound from the magnetosphere to the magnetosheath in the dusk sector on January 14, 2001. The dayside boundary layer was populated by magnetosheath electrons, but in not quite as high densities as in the magnetosheath itself. The Cluster ground track was calculated using the Tsyganenko 96 model which appears to be a strong tool for combining high-altitude satellite and ground observations, given that the solar wind conditions are known. This paper focuses on identifying auroral responses corresponding to boundary layer dynamics observed by Cluster. The first bundary layer encounter studied was a brief visit into a closed LLBL, likely due to a boundary wave that travelled tailward over the spacecraft. A corresponding equatorward and eastward movement was seen in the post noon aurora between Greenland and Svalbard. The second boundary encounter was into high-latitude cusp, and occurred as a consequence of a transient reconfiguration of the cusp. The cusp expanded duskward over the spacecraft into the late postnoon sector. NOAA-12 probed the 1630 MLT sector of this auroral activity, and measured a 1.4 keV electron beam located poleward of the 30 keV electron-trapping boundary. A sequence of three moving auroral forms emanating from this active region, are likely candidates for flux transfer events. The auroral signatures are discussed in relation to earlier observations, and appear to be an example of accelerated electrons/discrete postnoon aurora on open magnetic field lines.
