positive declination

So it goes from a positive declination to a negative one in under two weeks.

If the analemma is a graph with positive declination (north) plotted upward, positive equation of time (west) is plotted to the right.

At one of these points the Sun is moving from negative to positive declination, and that is the "vernal equinox" because it occurs on March 20 and marks the beginning of spring in the Northern Hemisphere, where most of man- kind lives.

Unlike the fixed stars, the Sun changes its position on the celestial sphere, being at a positive declination in summer, at a negative declination in winter, and having exactly zero declination (i.e., being on the celestial equator) at the equinoxes.
