Hello, I just recently came across this paper and I've been since reading everything I can find about Van Flandern's "credibility" and the controversies his proposals brought up. Still I'm yet unable to find a source to verify or disprove this assertion Van Flandern makes in his paper: "How then does the direction of Earth’s acceleration compare with the direction of the visible Sun? By direct calculation from geometric ephemerides fitted to such observations, such as those published by the U.S. Naval Observatory or the Development Ephemerides of the Jet Propulsion Laboratory, the Earth accelerates toward a point 20 arc seconds in front of the visible Sun, where the Sun will appear to be in 8.3 minutes." Is the above true? That the direction of Earth's acceleration goes toward the actual (not the visible) position of the Sun?
