Abstract A series of geomagnetic disturbances and cosmic ray variations caused by the McMath plage region 8818 in the latter half of May 1967 were examined. The systematic changes of the geomagnetic disturbances were observed as the relative location between the responsible flares and the earth changed during the half solar rotation period. The storm of May 25/26, 1967 was then studied in great detail on the basis of records from a number of magnetic and cosmic ray observatories. A large asymmetric main phase field in mid-and low-latitude regions (and thus an asymmetric ring current belt) grew rapidly during the first three successive polar magnetic substorms. The cosmic ray intensity variations during the storm consisted of the Forbush decrease and the ring current effect. The Forbush decrease had a marked north-south asymmetry during its developing phase.
