✦ Synopsis

The aurora1 frequency of occurrences (A) for the 20th solar cycle and for the geomagnetic latitudes 54"-63" N has been investigated in relation to sunspot numbers (R,), number of flares (F), the solar wind streams derived from the coronal holes (H) and the geomagnetic index (A,). The relationship between A and the other indices were found to be strongly latitude dependent. At around 57"-58"N, a drastic change in this relationship occurs, and an attempt is made qualitatively to evaluate this latitudinal variation.
