For once in my life, I was away on business during a new moon (usually when
i go away, it's a full moon - never seem to time it right).

Unfortunately I was sent out to the carribean island of Bonaire near the
coast of Venezuela. By some fate, the potential client that I was visisting
was into astronomy and took my up to the top of the island where it was
absolutely pitch black!

First time I had seen the southern cross and Omega Centauri! Venus was very
high in the sky and I was actually able to cast a shadow of my hand on to a
sheet of paper. I was so chuffed!!!

Tim/Pete,

There must be a way to nail this task so that there is no doubt about
the success of such a project. Time for my thinking cap to go on ....

That's why I animated the shadow. If there was ever any doubt it was
caused by sky glow, the motion of the shadow caused by the apparent
motion of Venus in the sky has eliminated this. There is room for one
further project but I'll leave that for update 3 ;-)

Venus does noit have an apparent motion,neither does Mercury,Mars
Jupiter or any of the other planets.The original heliocentric
astronomers did not have telescopes to use the motion of the inner
planets as they overtake the slower Earth as a way of affirming
heliocentric motion for the Earth and the other planets ,they used the
observed behavior of the outer planets against the stellar background
and by giving the Earth an orbital motion.,it allowed them to infer a
common heliocentric motion.

Pete here is correlating the motion of a shadow directly to the motion
of Venus when it is actually axial rotation he is looking at.With the
acknowledgement that the orbital motion of the Earth accounts for the
behavior of the planets nobody ever thinks about apparent motions of
the 'planets' except astrologers or what amounts to the same
thing,correlating the Earth axial rotation with the position of a
planet.

When the Western heliocentric astronomers talked of apparent planetary
motions they refered to the long term plotted positions that exclude
axial rotation.

"With regard to the apparent motions of the Sun and Moon, it is
perhaps possible to deny what is said about the motion of the Earth,
although I do not see how the explanation of precession is to be
transferred to the sphere of the stars. But if anyone desires to look
either to the order and harmony of the system of the spheres, or to
ease and elegance and a complete explanation of the causes of the
phenomena, by no other hypotheses will he demonstrate more neatly and
correctly the apparent motions of the remaining planets. For all these
phenomena appear to be linked most nobly together, as by a golden
chain; and each of the planets, by its position and order and very
inequality of its motion, bears witness that the Earth moves. . . . "
Rheticus

http://www.graviton.demon.co.uk/5planetsNr3520.jpg

The long term orbital motions of the planets and the speed at which
the Earth overtakes them and the inner ones overtake the Earth along
with 'transits' affirms that the Earth's orbital motion is between
Venus and Mars.The conjunctions above give no background context to
the Earth's motions or those of the other planets,it is only when the
Earth's orbital motion is considered ,then the system straightens out.

With your 'apparent' motions of Venus,you highlight just how deficient
contemporaries are in matters of meshing the motions of the Earth with
climatology insofar as the seasons and global climate rely heavily on
the motion of the Earth's orbital shadow over the course of an annual
orbit.

Before you go chasing Pete's shadows I suggest you look to your own
endeavor .The meridian line registers natural noon day after day
and then you apply the Equation of Time to equalise to 24 hour clock
noon.No figure 8,no tilting Earth,just plain natural noon and 24 hour
clock noon.

The heliocentric trick was to invent clocks which could maintain the
24 hour day and then after applying the noon correction,determine
position on the planet by using a correlation which keeps clocks in
sync with the axial cycle as 4 minutes for each degree of geographical
seperation making 24 hours/360 degrees.You have to love how they
tranfered the 'average' 24 hour day to a 'constant' axial cycle by way
of the Equation of Time.


" Draw a Meridian line upon a floor (the manner of doing which is
sufficiently known; and note, that the utmost exactness herein is not
necessary and then hang two plummets, each by a small thred or wire,
directly over the said Meridian, at the distance of some 2. feet or
more one from the other, as the smalness of the thred will admit. When
the middle of the Sun (the Eye being placed so, as to bring both the
threds into one line) appears to be in the same line exactly... you
are then immediately to set the Watch, not precisely to the hour of
12. but by so much less, as is the Aequation of the day by the Table.

Actually it is Venus' shadows I would like to chase. I have been
thinking about this exercise and challenge the past few hours and I am
very interested in Pete's project!

So they don't appear to move? They just stay stationary in the sky?

The orbital motions of Mercury,Venus ,Mars and the other planets are
seen to move against the stellar background over long periods.They are
resolved by an orbitally moving Earth between Venus and Mars,transits
take care of the inner planets overtaking the slower moving Earth and
apparent retrogrades are resolved by a faster orbitally moving Earth -

The apparent motions of the planets are always taken in context of
orbital comparisons ,at least by real astronomers,and not axial
rotation applied to the position of planets.

"If there was ever any doubt it was caused by sky glow, the motion of
the shadow caused by the apparent motion of Venus in the sky has
eliminated this" Pete

To link the motion of a shadow to the apparent motion of a planet may
get you a pat on the back from astrologers but it is about as far
away from the heights of Western astronomy as it is possible to
get,not just Copernican heliocentricity but Ptolemaic astronomy as
well.

This is great news. Expensive equatorial mounts obsolete. Ditto guide
cameras.

Hi Gerald,

Hope you are well?

Do you work for BT Ireland in Dublin by any chance?

It's just I've seen your posts here over the last few years, (very
interesting by the way, but I can't claim to understand what it is you're
trying to enlighten us about), and I saw there was someone wth your name
working for BT in Dublin, at least there was a year or so ago.

I was just wondering if it was you? If it was you, maybe you can try and
explain your points face to face over a pint on my next trip to Dublin?


Cheers
