Observations from the high-resolution spherical electrostatic analyzer experiment aboard ISIS I have been used to study large-amplitude irregularities at low latitudes in the topside ionosphere. The irregularities appeared as plasma depletions near the magnetic equator and were observed up to satellite apogee (3500 km). The altitude-local time distribution of the depletions was such that those at altitudes greater than 2000 km were found only in the post-midnight sector. This result agrees with the predictions of a simple MHD model for plasma bubbles drifting under the influence of gravity-buoyancy forces.
