WHAT’S UP IN THE SKY: Crossing the celestial equator

Today: At 5:30 a.m. PDT, the center of the Sun crosses the celestial equator and passes into the southern sky.

The celestial equator is an imaginary line that divides the sky into a northern and southern half. When the Sun is in the southern half of the sky, it takes a shorter path from rising to setting. It also does not get as high in the sky at noon.
