But I'm confused because you say question everything yet you're not even attempting to research SOHO while at the same time casting doubt on it's measurements. Are you going bother to find out if it has problems and/or falsehoods?
Aardwolf, there
are controversies about the distance to the sun which I outlined very early in this thread concerning how parallax is determined. Velocity = distance / time in relation to a "frame of reference", in this case the sun. If the distance to the sun is in question, so is velocity of objects passing by it. Since we can't stretch a tape measure to the sun, all we can do is give it our best guess. What has convinced you that the sun is 93,000,000 miles from Earth and what are the assumptions used to determine this distance?

Velocity can't be determined without a "frame of reference", or starting point.
