Plasma experiment on board of the ESRO satellite HEOS-1 observed heavy ions with energy per unit charge 2.5 and 4 times higher than protons. Observations refer to the driving piston of the interplanetary shock occurred on 31 March 1970. * Laboratorio per le Radiazioni Extraterrestri del C. N.

During periods in 1969-1971 when interplanetary flow conditions were quiet, 17 determinations of the solar wind Fe and Si abundances and 7 of the O abundance were made.
