О.I. Yagodkina and V.G. Vorobjev caused by precipitation of relatively soft electrons with an energy of <1 (Judge, 1972). Fig. 4 The auroral intensities in green and red lines along the geomagnetic meridian 3. Conclusions The data o f the meridian scanning photometers (MSPs) at Barentsburg (BAB) and at Lovozero (LOZ) and the interactive Auroral Precipitating Model (АРМ) were used. It is shown the possibility of АРМ for characterization the boundaries of auroral luminosity. The discrete auroral forms at BAB appeared within the AOP (auroral oval precipitation). Auroral luminosity at LOZ was located in DAZ and poleward of DAZ, in AOP. Spectral auroral characteristics in the pre-noon and after-noon sectors at BAB were studied from MSP data. It is shown that in the pre-noon sector during the 24 initial period o f the recovery phase o f substorm the red luminosity band filled the AOP region. In the after­ noon sector during the recovery phase of substorm the red band is more narrow and auroral arcs were observed near the poleward edge o f the red auroral band. The ratio I 6300 /I 5577 >1 in auroral forms testified of rather soft o f precipitating electrons. Acknowledgements.
