Peculiarities of the behaviour of λ6300 Å and λ5577 Åemission in day-time aurorae.
Abstract
Optical observations carried out on Spitzbergen are analyzed. It is shown that a significant enhancement of emission intensity occurs at 6300 A during 08-12 MLT with a simultaneous decrease in the 5577-A emission intensity. The region of intense glow at 6300 A in the prenoon sector has a width of 2-3 deg. Auroral arcs form at the equatorial boundary of this region and move 1-2 deg toward the pole.
