Dynamics of the equatorward boundary of the diffuse aurora according to data of the DMSP-F2 satellite
Abstract
DMSP-F2 data are used to study the dynamics of the equatorward boundary of the diffuse aurora (BDA) in the late morning sector (LT = 4.0-7.9 h) for 1978. The relationship between the BDA location and AE indices is analyzed statistically for the four seasons of the year, and the connection of the BDA boundary with the prehistory of the geomagnetic activity is investigated. A BDA time lag amounting to 1 h was found in the substorm-initiation phase while the time lag amounted to 4-5 h in the recovery phase.
