A feature of magnetic storms with a large main phase is that auroras appear in lower latitudes than usual. During a considerable part of the two storms of 23 September 1957 and 1l February 1958, the usual region of most frequent aurora was deserted. A temporary equatorward shift of the northern border of auroral activity was indicated. It was shown that the range of latitude in which auroras appear overhead intermittently expands and contracts; these changes were discussed in relation to the polar magnetic sub-storms. Red glows, seen occasionally in low and middle latitudes during large magnetic storms, become more intense as the activity of polar magnetic sub-storms increases. (auth)
