June Solstice 2013

The Northern polar coordinates do not ’tilt’ towards the Sun in the

coming days,they are carried around to a maximum distance to the

circle of illumination by the orbital behavior of the Earth.

While it is called ‘axial precession’ at the moment,the Earth does

turn once to the central Sun each year creating this effect as it does

with all planets,simply matching up the images of Uranus with the one

currently called ‘precession’ should be good enough for anyone -

Of course nobody else is going to describe what happens over the next

few days as daylight lengths reach their maximum in the Northern

hemisphere and summer kicks in for all people in the Northern

latitudes even as their bodies naturally adjust to this orbital point

of the Earth.The point is that we are astronomers by virtue of the

great cycles around which our bodies adjust to the day/night cycle and

the annual cycle,for those who care enough to discover why our mind

and body responds to these changes need only look at the specifics of

the Earth’s motions.It is these questions that got left behind and

lost in the empirical voodoo.

    ==================================================

    Never mind that, where in the sky is Sirius that you were

    ranting about six months ago? I can’t see it, where is

    your god hiding it?

    Lord Androcles, Zeroth Earl of Medway.

    When the idiots papabozo and Dork Van de faggot present an argument I cannot
    laugh at I’ll retire from usenet.

    Instead of the normal defining of the Solstice by the height of the

    Sun against the horizon,it is much more fun to look at the Solstice

    from a distance,besides the idea that the Earth tilts to the Sun gives

    the impression that the height of the Sun varies because the Earth

    ’tilts’ towards and away from the Sun like tilting a jug of water.

    The North/South poles are a few hours away from their maximum distance

    to the circle of illumination as the orbital behavior carries these

    planetary points where the Earth doesn’t rotate around in a circle to

    the central Sun,we can see it happen directly with Uranus where the

    poles now lie on the circle of illumination (Equinox)

    Although called ‘axial precession’,the Earth’s polar coordinates are

    moving to the exact same point in the following image,again,carried

    around by the orbital behavior of the Earth

    At the June Solstice,the North/South polar coordinates are situated

    roughly 5488 miles from the circle of illumination at their maximum

    distance so,on average,the polar coordinates will start to close the

    distance to the circle of illumination at a mean value of 30 miles day

    but change slower at this Solstice than at the December Solstice due

    to the Earth’s orbital position.

    It does raise many questions when it comes to orbital geometry but

    that is what makes astronomy exciting and challenging however,in the

    few hours before the Solstice it is an enjoyable pursuit to dwell on

    what is actually happening dynamically up to the event.
