Quizplus · Accepted Answer

At the equator, the observer is standing on the Earth's equatorial plane, which is also the celestial equator. The South Celestial Pole (SCP) is directly opposite to the North Celestial Pole (NCP) and located at declination -90 degrees. At the equator, the altitude of the celestial pole is equal to the observer's latitude, which is 0 degrees. Therefore, the observer at the equator sees the SCP at 0 degrees altitude.
