Scientific paper

It has been shown that the subvisual inhomogeneities in the 557.7 nm emission are observed equatorward of the low-latitude boundary of the 630.0-nm diffuse auroral emission. The dynamic variations in the optical structures are analyzed depending on the substorm phases. Before the expansion phase, whose source was formed at the meridian of observations, the inhomogeneities drifted southward at a rate of ~150-180 m/s. At the recovery phase of the substorm, whose epicenter was in the other longitude sector, the drift velocity was slightly less. The found velocity variations apparently reflect a reduction feature of the convection electric field penetrating into the inner magnetosphere.
