PROPAGATION OF THE SUDDEN COMMENCEMENT OF JULY 8 1966 TO THE MAGNETOTAIL

Abstract

Sudden magnetic field increase associated with the July 8 1966 sudden commencement (sc) was observed by the OGO 3 satellite in the magnetotail. By use of the IMP 3 and Explorer 33 observations made by Ness and Taylor of the interplanetary shock that caused the sc, it is shown that the magnetospheric propagationo#that the magnetospheric propagation of the field increase toward the tail is faster than the propagation of the interplanetary shock just outside the bow shock.
