TL;DR: In this paper, the authors examined a large database of postsunset plasma density measurements acquired during ∼ 15,000 equatorial crossings made by DMSP F9 and F10 in 1989 and 1991, respectively.

TL;DR: In this article, the authors discuss the roles of dynamo electric fields, over-shielding, and tidal effects as sources for the reported depletions in C/NOFS and ground-based measurements.

TL;DR: In this article, the authors extend a recent study of electric field penetration into the inner magnetosphere observed by the Combined Release and Radiation Effects (CRRES) satellite and the Defense Meteorological Satellite Program (DMSP) satellite F8 during the magnetic storm of June 4-6, 1991, to consider its ionospheric consequences.

TL;DR: In this paper, the authors report on plasma densities and electric fields measured by the C/NOFS satellite between 10 and 20 June 2008, and discuss relative contributions of gravity-driven currents, overshielding electric fields and disturbance dynamos as drivers of post-midnight depletions.

TL;DR: In this paper, the authors take advantage of the long history of plasma density measurements by a similar sensor on Defense Meteorological Satellite Program (DMSP) spacecraft to determine whether this change is typical of solar minima in general or unique to the present extended quiet time.
