Trough‐like plasma structures in the high‐latitude ionosphere near the polar cap boundary are investigated with EISCAT CP3 data and in‐situ satellite observations. Emphasis is placed on one interesting event occurring in the morning sector during the recovery phase of a moderate magnetic storm. The event features are probably ionospheric signatures of cusp processes caused by magnetic reconnection on the dayside magnetopause.
