Abstract
We have surveyed magnetic field data from the Ulysses spacecraft and found examples of magnetic waves with the
expected characteristics that point to excitation by newborn pickup He+. With interstellar neutrals as the likely
source for the pickup ions, we have modeled the ion production rates and used them to produce wave excitation
rates that we compare to the background turbulence rates. The source ions are thought to be always present, but the
waves are seen when growth rates are comparable to or exceed the turbulence rates. With the exception of the fast
latitude scans, and unlike the waves excited by newborn interstellar pickup H+, the waves are seen throughout the
Ulysses orbit.
