Observed path of the Sun

[Gerald Kelleher]

Many descriptions of the annual path of the Sun at the Equator in context of the Solstices/Equinoxes included that awful perspective. A reasonable person would immediately recognize that an observer at the Equator can't distinguish between winter/summer as they exist at a latitude which divides the hemispheres.

It is also a perspective which plagues all other descriptions. A person at the Equator turns at a rate of 1037.5 miles per hour so when they exit the circle of illumination (sunrise) until they re-enter the circle of illumination (sunset) 12 hours later the observer has covered 12,450 miles across the fully illuminated face of the Earth.As there is no meaningful daylight/darkness asymmetry at the Equator, the graphic and the explanations of the North/South path of the Sun are rubbish and disruptive for the technical details of the Earth's motions.

There are many of the same false graphics out there so no wonder the Caltech students here never stood a chance -

How an observer at the Equator decides whether it is the winter or summer Solstice by the position of the Sun given that they straddle the hemispheres and when it is the winter solstice in the Northern hemisphere or summer solstice in the Southern, they both happen at the same time. This is, of course, all nonsense but obviously whatever it takes to justify celestial sphere observing.

The safe cloudy nights forum caters for the limited version of astronomy, an astronomy that never broaches cause and effect with terrestrial sciences since they tried to bypass the central Sun for the motions of the Earth and appealed to circumpolar motion of everything, including the Sun in RA/Dec -

Again, I understand many are a product of their instruction as students and would not dare question the validity of their certificates and degrees but such is the paper thin difference between genuine astronomy with all its causes and effects and celestial sphere rubbish.

The heart does sink sometimes despite seeing the way through all this to the eventual recovery of astronomy. The rise of celestial sphere software was indeed rapid as were descriptions based on that clockwork generated and homocentric view -

Basically borrowing from the tropic of Cancer/Capricorn and split by the Equator, it escaped into the celestial arena where they even pivot the circle of illumination to suit the Sun over the latitudinal points -

Somebody else must feel something when confronted with such childish notions that were allowed to fester, even in the lifetime of this newsgroup. So where to now ?.

Gerald, if you do not understand this extremely basic and easy-to-understand graphic then you have no business lecturing people about the dynamics of the Earth and Sun. This is drop-dead first-thing-you-learn in grammar school stuff...

Like everything else, the graphic is a fraud as are the people who promote it, a notion so abhorrent to reason that it takes really damaged individuals to go along with it -

I take pride in human reasoning but that, that represents something which would break a person's heart as it turns the RA/Dec version of the motion of the Sun into reality. To manipulate imaging in order to promote a pivoting circle of illumination is criminal and especially as it is done through the space agency.

As for you Paul, you feel nothing and that has been your problem all along.

You can see Eastern Africa throughout, they are simply keeping North at the top of each image, which is not "manipulating" anything.

Indeed, if they kept the circle of illumination horizontal, do you know what the sequence would show?

The North Pole tilting! Ha ha!

That is out and out fraud but other than it is generated from a celestial sphere ideology there isn't much more that can be said other than it takes a damaged mind not to be sick from the assault on the eyes and mind.

It is not generated from a celestial sphere ideology, it is generated by a camera on a satellite in geostationary orbit above Africa.

You would see the very same thing with your own two eyes if you were up there.

Well, it's true that they only took one frame per day, so it's always the same
time of day in Africa even though the movie shows a major part of a year.

So one has to understand that it eliminated the rotation of the Earth in order to
illustrate its point about the consequences of the Earth's orbital motion.

The Earth with a 0° inclination and a pivoting circle of illumination would be the end of astronomy and finishing this newsgroup for good. The fact that observations are manipulated to bring it in line with celestial sphere thinking, if it can be dignified at all as thinking, is outright fraud.

I would have nothing to say to anyone here again as the damage to astronomy is total.

You must have awful bother reading maps, what with them being artificially manipulated to have North at the top and the Equator horizontal.

Like these images.

[Gerald Kelleher]

"Explanation: When does the line between day and night become vertical? Tomorrow. Tomorrow is an equinox on planet Earth, a time of year when day and night are most nearly equal. At an equinox, the Earth's terminator -- the dividing line between day and night -- becomes vertical and connects the north and south poles. The featured time-lapse video demonstrates this by displaying an entire year on planet Earth in twelve seconds. From geosynchronous orbit, the Meteosat satellite recorded these infrared images of the Earth every day at the same local time. The video started at the September 2010 equinox with the terminator line being vertical. As the Earth revolved around the Sun, the terminator was seen to tilt in a way that provides less daily sunlight to the northern hemisphere, causing winter in the north. As the year progressed, the March 2011 equinox arrived halfway through the video, followed by the terminator tilting the other way, causing winter in the southern hemisphere -- and summer in the north. The captured year ends again with the September equinox, concluding another of billions of trips the Earth has taken -- and will take -- around the Sun."

Not just fraud but perhaps criminal incompetence with a very specific celestial sphere approach.
