On March 1, 1981 the spatial distributions of ionization and luminosity were monitored at Chatanika, Alaska with the incoherent-scatter radar, an all-sky television system, and meridian scanning photometers. The radar detected discrete regions of enhanced E--region ionization at subauroral latitudes, more than 3¿ equatorward of the diffuse aurora. The high-resolution all-sky television measurements at 427.8 nm showed that the luminosity pattern resembles multiple auroral arcs; they are narrow in latitudinal width and they extend from horizon-to-horizon in an east-west direction. These observations indicate the existence of a subauroral source of electron precipitation that is both narrow in latitude and extended in longitude.
