The waves are intrinsically left- hand polarized in the plasma frame, but appear both LH and RH polarized in the s/c frame, with highly variable frequency, suggesting they were probably generated by perpendicular pickup. The lower power and smaller occurrence rate of RH waves , and the decrease of wave power with heliocentric distance all support the closer-to-Sun generation and
