<P> The solar noon shadows of objects on points beyond and below subsolar points will point towards true north and true south respectively only when the solar declination has its maximum positive ( δ ☉ = + 23.44 ° ) or maximum negative ( δ ☉ = − 23.44 ° ) value . On the other hand , on the equinoxes when the sun is neither declined north nor south ( δ ☉ = 0 ° ) and solar time noon shadows point NNW north of the equator and SSE south of the equator on the vernal equinox ( and point NNE north of the equator and SSW south of the equator on the autumnal equinox ) . </P>
