You are looking at the apparent sun at sunrise, not the actual sun. Its projection upon the atmoplane.

The apparent sun at sunrise is on the rim of the sun's area of light and is racing along the equator or your latitude line to you. However straight your latitude line is in your local area where you can see will be how the sun appears.

If you were on the equator, and there was a race car (or jet ski) racing along the surface of the earth to you on the circular equator line, and you only see it until it is nearby, would you see it from the East or very near the East? If so, there is your answer.

Consider what happens when you walk into a dark movie theater. There is a projector at the back of the room, shining an image on the screen. When you look at the screen, you are not looking in the direction of the ultimate source of the light. The light from the projector doesn't need to bend at all in that scenario, just reflect.

Where is the actual sun?

Probably further North.

Wise did have an interesting thread last year where not all of the shadows in daylight scenes were coming from the sun, and seemed to be coming from another direction. He had a bunch of examples of that happening. Maybe it's somewhere on the other FES website.

In the movie projector example above, there is still recurrent light coming from the projector source. If you look back at the projector, it shines light on you, despite you not being between the projector and the screen. It would be interesting if it could be determined which other direction the shadows were coming from in that thread, which I can't seem to find at the moment.

Hi, new user here! I saw this projection explanation from Tom Bishop in edby's sunrise thread and what puzzles me about this whole apparent sun business and it being a projection of the real sun is the behavior of young sunflowers. They track the sun through the sky, as this article and the supporting study show ( )basically the plant has a circadian rhythm, it's controlling its growth through its internal clock, turning to get the most sunlight. But young sunflowers follow the apparent sun, but that's a projection according to FErs, so why would it follow that, shouldn't it follow the actual sun since that's the source of the radiation? Shouldn't we see a difference between the apparent/projection sun's position and the actual source of radiation, or what the sunflower's looking at?

Here's a time lapse video of a young sunflower following the sun. The sunflower footage starts at about 0:37 seconds.

We are smarter than those scientists.
I see multiple contradicting explanations. You guys should have a pow-wow and figure out how your model works.
