USING eight magnetic stations in low latitudes, hourly values of Dst are determined for the IGY. Three-hourly mean Dst values are compared with corresponding values based on Kertz's Dst indices. Three-hourly mean Dst is also compared with ap indices.

It is found that Dst correlates well with ap in gross features and that during magnetic storms activity represented by ap recovers more rapidly ... The origin of magnetic fields in the universe is a very important unsolved problems in cosmology
