Simultaneous observations of low-energy solar protons (1−40 MeV) by HEOS-2 in the northern high-latitude magnetotail and by other spacecraft in interplanetary space during the solar proton event of 8 June 1972 are presented. The results indicate that solar protons enter that magnetotail lobe which is not well connected to the interplanetary magnetic field — with respect to solar-particle entry—preferentially close to the Earth (|X|) < 10 R E ) rather than farther downtail. The particle density gradients measured in the tail lobe suggest that the particles enter there not only across the polar magnetopause, but also from the neutral sheet
