Dawn being the transition from darkness to daylight is a consequence of a surface rotation, at our latitudes it happens once each 24 hours as the planet turns once.

For once people can appreciate that twice a year there is a day on the Equinox when there are two distinct sunrises correlating with distinct rotations with their own dynamical traits.

The Earth doesn't tilt towards and away from the Sun to cause the seasons or the events that move between the main Solstice and Equinox points , the planet has two distinct rotations that are now visible to a large degree -

Try explaining polar dawn with a surface rotation and see how any person here or anywhere else gets on.

.... not exactly news, but this is why there are 366.25 rotations per year, because that extra 'unique' rotation is WRT the fixed stars!

This is designed for children and interested adults who wish to discover the reasons why our home planet has two separate day/night cycles and the surface rotations behind them. The unique day of the Equinox produces two distinct events where the Sun comes into view with polar sunrise being one of the most important days of the astronomical calendar -

The Earth doesn't tilt towards and away from the Sun, by the very nature of terrestrial effects requires two distinct surface rotations to account for experiences of the seasons at our latitudes or the polar day/night cycles at the respective poles.

Perhaps you are better suited to the other threads which allow you to vent your stock phrases at contributors who are literally begging for that type of attention.

The sky gets very busy around the area where the Sun comes into view at
dawn, the difference being that the unique polar dawn at the South pole
lasts for a considerable period of weeks when the Sun eventually shows
itself on September 22nd as the Earth has a unique surface rotation as a
function of its orbital motion -

An atmosphere that lacked color for so long, even when the moon passed
before it on the June Solstice now takes on that amazing glow for those
who admire the event daily at sunrise and sunset.

When people get jaded of opinions designed to diminish individuals or
humanity itself they can turn to that intimacy which is their
astronomical inheritance - something to love in a world when men no
longer feel what is important. Again,a unique dawn that happens once a
year at that location.



It shows at about 8 pm UT on the 21st and takes until about 8 am on the
23rd to clear the horizon. During this period it moves 1 and a half times
around the horizon. Can you explain why?

This is really only for people who haved lived and live as individuals -
the Sun coming into view on the Equinox for the first time in 6 months is
a result of a Great rotation, one that now can be seen directly from an
orbiting satellite -

https://www.youtube.com/watch?v=CFrP6QfbC2g

The same change in colors with an anticipated appearance of the Sun as
the planet turns and it does so in two distinct ways so that on September
22nd there will be two distinct types of sunrises , one going on due to
daily rotation and the other as a function of the planet's orbital motion.

http://www.usap.gov/videoclipsandmaps/spwebcam.cfm

That soft glow of orange and red will be matched soon enough at the
Northern equivalent as the glow marks polar sunset.


Why can't you answer my question? You can see it's true form the webcam
(although there seem to be very few times when it's live). You can't deny
the truth. So explain it!

Dawn and sunrise as they happen in two distinct ways is a product of a
turning Earth and ,for the first time, an entire generation of kids can
watch Antarctica cross the sunlit fact of the Earth while watching it
rotate in its daily rotation. The surface point called the South pole is
unique as that in the one surface point on Antarctica where the Sun is
present and absent for 6 months at a time -

https://www.youtube.com/watch?v=CFrP6QfbC2g


Something different is happening around an area of the planet where few
people live yet modern imaging makes it possible for everyone to share
the spectacle or a miracle.







Modern imaging allows us to watch the sun seem to circle the horizon every
Greenwich Mean day from the South Pole. This demonstrates that the South
Pole rotates with the rest of the Earth. It also allows us to see the
apparent rotation of the stars around sigma octantis every sidereal day
during the south polar winter. This demonstrates the true rotation of the
Earth.
If you want anybody to agree with you you have to explain these facts and
not ignore them.

Refusing to explain why this could happen in your universe means you are
lying to the world by omission. It's also why not a single person out of
the billions of possible converts believes you. You are doomed to to keep
repeating the same ridiculously simplistic misunderstandings until you die.
Sit down. Assume the other side (that's ever body else ) is right. Think of
reasons why they are wrong. The main thing you have to do is show how the
two verifiable observations I mantis end above are wrong. If you can't do
that nobody will believe you and you will spend the rest of your life as a
mildly amusing crank who can't convince even his own family.






"Mantis" should of course be "mentioned".


The storm is over and the sky has cleared to reveal the long dawn that ends with the day of two different types of sunrises on the September Equinox.

Those who can be inspired will find a resonance within themselves and feel the significance of the event as something new and a gateway to many exciting discoveries -

Default Polar Sunrise

The long night is over as the South pole begins its final approach to the circle of illumination with the Sun coming into view next week -

http://www.usap.gov/videoclipsandmaps/spwebcam.cfm

The journey through polar night is therefore complete with the two distinct types of sunrises on the same day closing out that 6 month trek which included a full moon on the Solstice.


There is a lot of the usual chatter about God among those who make a racket for themselves in drawing attention to their opinions but none of it ever connects the individual with the Universal or man to God as an inspirational connection. Insights like these return a balance as it uses contemporary imaging and human curiosity to create a narrative that wasn't there before, in this case the dual surface rotations of the planet to the Sun and how we see and experience them on the surface of this gorgeous planet.

Next week there is the unique day of two separate sunrises with the colors changing in a sky that hasn't seen any for about 5 months -

http://www.usap.gov/videoclipsandmaps/spwebcam.cfm

It is astronomical poetry as two distinct types of dawn now present themselves to observers and made possible by 21st century webcams.

The Earth doesn't tilt towards and away from the Sun nor does the Sun cross an imaginary celestial Equator, what happens is that two surface rotations combine on September 22nd to create dual sunrises within the same 24 hour day.

1461 re-invents the one stick test to replace the long outdated two sticks test.

Sod the azimuth! Just feel that altitude!

Now all we need is for him to re-invent the well test for solar altitude and we're golden!

The Equinox is defined as the day where there are two separate sunrises and sunsets as the Sun comes into view for the first time in 6 months at the South pole while its Northern counterpart the Sun is out of view until the March Equinox -

https://www.youtube.com/watch?v=okw6Mu3mxdM

The polar points offer a window into the orbital motion of the Earth and the fact that our planet turns to the Sun as a function of its orbital motion unlike the moon's orbital motion of the Earth which retains the same face across its monthly circuit.

This is the first year the dual rotations of the Earth can be seen in its entirety even if there are no observers,apart from myself, around to appreciate this great astronomical advance in imaging and in interpretation -

When something new,creative or productive comes along the great Christian sayings begin to make sense -

"No one lights a lamp and puts it in a place where it will be hidden, or under a bowl. Instead they put it on its stand, so that those who come in may see the light." Jesus

It hardly looks like astronomy however ,with polar dawn now ell established as the stars disappear from view, the Sun will come into view in a few weeks as the planet continues to turn as a function of its orbital motion.

There is no proof,evidence or any other legal jargon that occupies the rabble at lower latitudes, there is just the predictable appearance of the Sun on the Equinox for the first time in 6 months and reflecting one of two surface rotations to the Sun that go on simultaneously.

Let the crude strut around with pretenses and error, this insight is for those who are not afraid of being individuals and alone.


-61 C deg?
Not for me!

This annual spectacle which takes on the September Equinox at the South pole is the result of a turn Earth as opposed to the 'tilting' Earth. On a day when all the articles in the media announce a celestial sphere description of the Sun crossing the celestial Equator this forum provides the only accurate description of the central Sun coming into view as the entire surface of the planet turns parallel to the orbital plane with the South pole a unique location in this respect.
