“…The classification has been applied to all data of large solar flares published in Solar Geophysical Data, and the corresponding catalogue of isolates flares and flare series has been compiled (Ivanov et aL, 1979). According to the new classification of flare situations if the time spacing between the flares were greater than 2.5 days, they are classified as isolated flares.…”

“…A method of determining Earth's position relative to an isolated flare-generated stream was also suggested (Ivanov, 1981), and the typical scales of the cross-sections of isolated shock waves have been estimated . The data of 22 isolated flares were used, and it was concluded that the ratio of typical scales along (i.e., parallel to) and across (i.e., perpendicular to) the NS was > 2.5.…”

Occurrences of interplanetary shock waves near the Earth after the powerful isolated flares of 1957-1978 are investigated. The close connection between the occurrences of shock waves and the positions of magnetic axes of bipolar groups of sunspots is suggested on the basis of a statistical study. The shock waves are principally observed when the Earth finds itself near the planes that are projected through the flares in parallel to the appropriate magnetic axes of the nearest bipolar groups. This regularity is interpreted as an indirect argument for a three-dimensional geometry for the interplanetary shock waves which, when projected on these flattened to corresponding planes, are traces of large circular arcs. The typical angular scales of isolated interplanetary shock waves are estimated as ~ 150 ~ and ~ 30 ~ parallel and perpendicular, respectively, to the magnetic axes correspondingly.
