When Does The Sun Rise?

Is it actually a sunrise before or after the sun makes it fully over the horizon?

You can plausibly define sunrise as either the appearance of the lower limb or the upper limb over the horizon; the upper limb (i.e., first actual appearance) is more common. Because of atmospheric refraction, the appearance will be a few minutes before the sun is actually at 90 degrees to the vertical.
