How many degrees is the sun below the horizon at sunset?

Answer 1

If I am looking at the horizon when the sun sets, then the sun is zero degrees below the horizon (unless you wanted to get really exact, and figure out the diameter of the sun, the distance that the sun is from the Earth, etc) At any rate, the Sun is ON the horizon at Sunset, by definition, and therefore zero degrees below it.

Answer 2

According to the US Naval Observatory, "Sunrise and sunset conventionally refer to the times when the upper edge of the disk of the Sun is on the horizon, considered unobstructed relative to the location of interest. Atmospheric conditions are assumed to be average, and the location is in a level region on the Earth's surface."

And, "For computational purposes, sunrise or sunset is defined to occur when the geometric zenith distance of center of the Sun is 90.8333 degrees. That is, the center of the Sun is geometrically 50 arcminutes below a horizontal plane. For an observer at sea level with a level, unobstructed horizon, under average atmospheric conditions, the upper limb of the Sun will then appear to be tangent to the horizon. The 50-arcminute geometric depression of the Sun's center used for the computations is obtained by adding the average apparent radius of the Sun (16 arcminutes) to the average amount of atmospheric refraction at the horizon (34 arcminutes)."

Answer 3

O or 1 degree?

Answer 4

If you can see the sun, it is ABOVE the horizon.
