latitude are marked, and along the horizontal one — the uni versal time. The radioaurora is shown by the vertical lines and their density corresponds approximately to the radio aurora amplitude. The solid lines are the location of the low borders of arcs , the thickness of the lines expresses roughly the brightness of the luminosity. Tyo upper pictures in Fig.5 illustrate the earlier described activity of the auroras. Here one can see the equatorward and the poleward motion of the diffuse band. The radioaurora is localized an the pole side of luminosity and they are enough Jointly mo ving synchronously. Hear 01.19 — 01.20 UT one can notice considerable decreasing of the meridional size of the radio aurora. A new broadening of the radioauroral region corres ponds to the onset of an active phase of the microsubstorm. At 01.20:20 UT the leading border of the auroral loop crossed the Loparskaya zenith. Just after the passage of the loop across the Loparskaya' meridian a new. signal appeared on the- equatorial boundary of the radioauroral band. That sig nal filled exactly the all Inside part of the loop. The loop travelled to the east but Its northern and southern bounda ries were seen along the meridian approximately till Of.20:30 UT. Those boundaries began to move to the north and owing to it the radioaurora filling of tha-t new non—leading part of the loop began simultaneously Its northward mcrtion. Then the bordered with the northern and southern arcs of the loop not be^ng overlapped with the arcs as well as before. The similar features were observed at the passage of the second loop at 01.28:30 UT. But there the radioauroral filling of the loxjp w a ' asymmetrical and was shifted to the equatorward side. The both loop passages were accompanied with negative bursts of the magnetic H—component in Loparskaya shown In Fig.2 by arrows. The first loop appeared in the STARE-region at 01.12:50 UT as a bright fold. Itcould be seen in the upper picture of Fig.6. In the neighbourhood to the fold the irregularity drift velocities corresponded to the southeastern electric field b e ing~60 mv/m. The east component of the electric field was ~ 20—30 mv/m. The loop drifted to the east and its 22
