Abstract: Large-scale coronal structures (helmet streamers), observed in the white-light solar corona during total eclipses, are mostly seen above prominences. These streamers are supported by the global magnetic field of the Sun. However, the distribution of prominences over a solar cycle shows both the poleward and equatorward migrations. The location of observed white-light coronal streamers during total eclipses in the period 1988 --1998 will be compared and discussed with that of prominences. It seems that the distribution of the above mentioned streamers matches the distribution of prominences and shifts together with prominence belts to the poles. A possible scenario for a such development is described and discussed.
