Sparse Measurements: IMP-8 Ground Magnetometers [Arnoldy, 1971] Signature in the interplanetary medium for substorms. Points toward linear driving by IMF Bz versus triggering of geomagnetic activity. Pointed to the need for simultaneous observations in two different locales. Many related studies followed, nearly 300 citations!

Opportunistic collection of s/c, spread around geosync +: ATS-6 (UNH Hot Plasma!) SCATHA GEOS GOES LANL Several 1981-83 papers, especially: Arnoldy et al. 1982, Substorm injections related to positive Dst; and 1983 “Longitudinal structure of substorm injection events” Anticipated “sawtooth events” Raised issue of tail behavior in storms, substorms. Pointed to s/c clusters… Multipoint Measurements ca. 1980 Arnoldy: Multipoint Measurement Pioneer
