The farthest manmade object comes through !
Yep, Voyager's measurements of the Terminal Shock (wave) of the solar system may be the cause of the CBE's measurement deviation. I wonder how this may affect other astronometric measurements ? Gravity lensing, solar wind lensing.. hmmm !
Or is it just LGM out there with the proton wind equivalent of lightshow handpuppets playing silly buggers with us ?
