Abstract. More than 60 breakups, including weak activations of
the pseudo-breakup type, moderate breakups, and events of very strong auroral
activity, were analyzed using ground-based TV data, together with satellite
auroral images. We studied the fine subvisual details of spatial and temporal
dynamics of active auroral forms and surrounding diffuse luminosity, both in
the longitudinal and latitudinal directions of the TV camera field of view. For
all types of breakups a close interconnection of auroral activity was found
across and along the auroral oval.
