Results are presented of the artificial optical emission of the atomic oxygen red line(the radiation of level O(1D) with a wavelength of 630 nm) from theHF-pumped ionosphere, obtained in September 2004 at the SURA heating facility situatednear Nizhny Novgorod, Russia. For vertical pumping the airglow patch was increasinglydisplaced to the north, up to 7–8°, with increasing reflection altitude. Forlarge brightness of the emission, the airglow patch started to develop at the northernedge of the pump beam and later expanded to the south. These effects are attributed tothe precipitation of supra-thermal electrons from the pump wave upper hybrid resonancealtitude to lower altitudes where excitation of the O(1D) level is moreeffective due to the larger density of atomic oxygen, and the O(1D) lifetimeis shorter. For a pump beam inclination of 12° to the south, the optical spot wasdisplaced by 4–5° to the south relative to the straight-line projection of thepump beam onto the sky. This exceeds that expected from the ray tracing and may berelated, most probably, to the so-called "magnetic zenith" effect. In addition,mid-scale (1–10 km) magnetic field-aligned structures were observed in the pumpedvolume of the ionosphere. The east-west motions of the airglow patches are also analyzed
