The effect at the December solstice is more pronounced than for the June one.
The Sun crosses the celestial equator (0[degrees] declination) moving northwards at the March equinox, reaches its maximum northerly position over the Tropic of Cancer (23.44[degrees]N) at declination +23.44[degrees] at the June solstice, returns across the equator at the September equinox and reaches its most southerly point at the December solstice over the Tropic of Capricorn (23.44[degrees]S) of declination -23.44[degrees].
January 1st comes about 10 days after the December solstice
and a few days before Earth's near point to the Sun each year.
They found that the axis of the temple follows an azimuth of 114[degrees], which aligns with a distant marker that indicates the point where the Sun rises on the December solstice
, the time when summer melt-water from the Andes Mountains would peak and flood the farmland.
This means that at the June solstice the Sun is 23 1/2[degrees] north of the equator, and at the December solstice
it's 23 1/2[degrees] south.
The latitude on Earth over which the sun hovers on the December solstice
is still called the Tropic of Capricorn, even though precession long ago moved the solstice into Sagittarius.
That's only a few hours after the December solstice
and a few hours before full Moon.
(We get a similar swell of questions around the December solstice
.) The least time- consuming way to explain this disparity is to have a picture of the analemma handy, as described in the December 1998 issue of this magazine (page 124).
