Question 23

A lunar eclipse occurs when the Moon enters Earth's umbra. It is visible from any location on Earth where the Moon is above the horizon (location B, as it faces the Moon's direction). A solar eclipse involves the Moon blocking the Sun from Earth's view, which is not the case here.

Star trails are caused by Earth's rotation. Polaris (the North Star) is near Earth's north celestial pole, so stars appear to rotate around it. The Moon, Sun, and Alpha Centauri are not fixed at the center of such trails.

Answer:

(4) A lunar eclipse is occurring and can be seen from location B.
