It can be seen then, as time goes on, light from a given source becomes increasingly blue shifted when observed nearby. Howevr, from a distance it will appear red shifted since the observer will be in a relatively higher blue shift state at his observation post.


What does the author of that think he's saying? Sounds like he's mixing up red shift from expansion with red or blue shift due to relative motion - none of which applies to the sun since its distance from the Earth is relatively constant, and far too small for universe expansion to be relevant.
