The answer to your question is yes, it's called SOHO.

That is truly marvelous -- sonograms of the sun! I would imagine that observing far side phenomena in this manner would also be subject to varying degrees of distortion, all the better to understand the different densities and internal structure of the sun. The sun is hardly homogeneous.

Ulysses is another sun observing satellite, although in solar polar orbit. I am curious to know if its elliptical orbit, perpendicular to the equitorial plane and extending to the orbit of Jupiter, precesses along the zodiac. I am also curious about the orbit's eccentricity. Do you have any sources to answer those two questions?
