Abstract The authors report on observations of ion conics at altitudes below 10000km. They observe the cone angle to decrease with altitude, and conic temperature to increase with altitude. The former effect is not consistent with simple adiabatic models. The authors interpret their observations to suggest that what is being observed is a nonconservation of the adiabatic invariant along field lines, and hence some type of transverse acceleration process which exists over a wide altitude range.
