Abstract
Spectral-polarization analysis of interval of pulsations of diminishing periods (IPDP), observed on November 9, 2017 at Istok observatory have been carried out. Pulsation characteristics calculated from five-minute sets of magnetic data are compared with changes in the intensities of 486.1, 557.7, and 630.0 nm emissions in the north, south, east, west, and zenith directions as well as with all-sky camera images and keograms made at the same wavelengths. It is shown that the frequency of the pulsations increased when regions of the intensified emissions expanded toward the equator. A possible relationship between the appearance of east-west elongated auroral arcs and the IPDP spectral composition is considered.
