I'm not convinced about this refraction talk, I'm not sure refraction is capable of moving the sun that distance (>1°). However, it's unnecessary. Here is a diagram (exaggerated) to show how the selenelion works:

Obviously it's not to scale, but that's the basic idea. As you can see, it can only happen at sunrise/sunset, and lo and behold -- all of Tom's photos show the eclipse happening in twilight.
Also, the vast majority of lunar eclipses happen at night. Why should this be the case in FET? It makes total sense in RET. And why do none happen at midday?
Come to think of it, why in FET do we never get a full moon at midday?
