Sun Sinks South.

10-21-11 SHORT HILLS: The last rain left us with another 1.15 inches. Today is overcast, in the fifties with little wind. It’s supposed to be dry for the next few days.

We are now about one month past the Automnal Equinox and the sun is halfway, almost 12° south of the Equator, on its way to the Winter Solstice when it will be 23.5° south of the Equator. From the northern hemisphere viewpoint, the nadir of its excursion from Tropic to Tropic. Two months ago, August 21, or so, the sun was 12° north of the Equator. This dramatic N-S change contrasts with the long dwell time in each hemisphere, N in summer and S in winter, that lasts four months each. That’s why it’s getting cold and dark.
