You are addression only one of at least three effects on the apparent position of the sun.

It just so happens that the one that I mentioned (due to the earth's transverse velocity) is the single biggest cause of apparent angular displacement of the sun's position.

Stellar Aberration, which is due to the earth's transverse velocity (which is about 67K mph) causes "20.something" arcseconds of apparent displacement. The surface speed at the equator due to the earth's rotation is about a thousand miles an hour - so that changes it by 1 part in 67. Then the Sun very slightly orbits its barycenter - but it doesn't move much and it doesn't move fast - so the light-time correction for the sun's motion is completely dwarfed by the 20 arcseconds due to Stellar Aberration. (I did all the math and posted it to FR a while back - let me know and I will find it and point you to it.)

So it is true that I only mentioned one of at least three causes of apparent angular displacement of the sun - but the number I gave you of 21 arcseconds is the sum of all of them rounded up to the nearest whole arcsecond. And for your information, there are 360 decrees in a circule, 60 arcminutes in a degree, and 60 arcseconds in an arcminute - so 1 degree is 3600 arcseconds. So LeGrande's 2.1 degrees converted to arcseconds is an enormous 7560 arcseconds - huge compared to the actual 21 arcseconds.

I'm not sure if you're familiar with science at all, but 7560 is waaaaaaay different then 21 and it is absurd to claim what LeGrande is claiming without providing proof.

The fact is that there are some people who will teach to others an out right incorrect idea and refuse to even answer questions that might show how wrong the idea is. And this is the cause of the current state of shambles of science in our classrooms.
