A subauroral and mid-latitude view of substorm activity
Experimental observations from a variety of sources made during a substorm period near 0900 UT on January 2, 1971 have provided evidence confirming mid-latitude and subauroral phenomena associated with magnetic substorm activity. A review of these observations, including ground and balloon observati...

Experimental observations from a variety of sources made during a substorm period near 0900 UT on January 2, 1971 have provided evidence confirming mid-latitude and subauroral phenomena associated with magnetic substorm activity. A review of these observations, including ground and balloon observations made near L=4 at the conjugate stations Siple, Antarctica and Roberval, Canada and data obtained from the synchronous-orbit satellite ATS 5 positioned about 2 hours west of the Siple, Roberval meridian, is presented. During the hour before the reported correlated bursts of X rays and VLF noise (Rosenberg et al., 1971), the plasmapause appears to be displaced towards the equator from Siple; resonance conditions along the field lines at Siple were favorable for the observation of results of magnetospheric wave-particle interactions involving electrons with energies exceeding 30 keV. The correlated observations are a potential source of information concerning the relationship of ULF and VHF noise activity to the magnetospheric particle population at middle latitudes; the injection and subsequent drift of low and medium energy electrons during substorms; and enhanced particle precipitation deep within the plasmasphere during substorms. |
