Polar night and a full moon

Really like the image with a person walking in reflected sunlight at the South pole presently -

Twice a year it happens that two distinct noon events happen on the same day on Earth with polar noon complimenting daily noon that all here experience. As long as that individual remains at the South pole he can only experience polar noon while those at lower latitudes can only experience daily noon.The same with sunrise and sunset as there are two distinct days within an annual orbit when polar sunset and polar sunrise are present within a weekday (Equinoxes).

This is not a matter of human conventions, there are technical reasons which shade off into planetary climate and such things as Arctic sea ice evolution and the seasons which maintain clear and precise perspectives. Of course this has nothing to do with trivia or the dishonorable who enter the discussion of this topic.

Last time I checked there was a noon every day. Of course at the poles it's
alway noon by the clock since all meridians converge and you can choose
whatever time zone you like.

This is not for you or any of the other ineffective people arguing over pronunciations but then again I have yet to see interest in the singular polar day/night cycle with its distinctive divisions of sunrise/sunset on the Equinoxes and polar noon and polar midnight at the Solstices.

It is approaching polar midnight at the South pole as the surface continues to turn as a function of orbital motion to a position when the South pole is midway between the circle of illumination and thereby polar noon.

For whatever reason people just do not want to know however nobody can claim the title of astronomer if they can't manage to account for something so straightforward and so obvious as the polar day/night cycle and its rotational cause. However important it may be it is far more lovely to consider and that is what makes us human in recognizing something pleasing when we see it.

Its cause is not rotational; its cause is revolutionary!

When the Sun first appears on the Equinox at the South pole it draws attention to the fact that the small circumference of the observer's horizon is exiting the circle of illumination and moving into solar radiation for a constant period of 6 months . This area continues to expand after the Equinox until it reaches its maximum area at the Solstice and corresponding to the planet's Arctic or Antarctic circles before contracting after the Solstice. It is this expansion/contraction of area,among other points, which focuses the observer on an surface rotation as a property of the orbital motion of the Earth.

Maybe in a world that is rapidly changing for good and for otherwise that focusing on a barren place like the South pole produces so much information that effects habitable latitudes and thereby provides a refuge for calmer, productive and more creative minds.

Even the 10% drop of luminosity created by the waning moon shows up at te South pole compared to a few days ago -

Already the tilting Earth explanations are appearing before this month's Solstice event but how much more enjoyable to explain the expanding circles where the Sun is constantly in view or constantly out of view as both poles turn towards their midpoint to the circle of illumination.

At this case it wouldn't be a case of finding the old 'tilting' Earth explanation wrong but more to exploring the more productive explanation of a distinctive surface rotation arising from the orbital motion of the Earth. Brings some life back into an era of 'settled' science among other things.

But the Earth has an atmosphere, delaying changes in temperature
compared to changes in insolation. This delay, however, is not
exactly half a season.

And this delay cannot be accurately predicted either. Therefore
astronomical seasons are different from meteorological seasons. In my
country, Sweden, there can simultaneously be meteorological winter,
spring, and summer, in different parts of the country.

If you limit your choices of local time to one of the official time
zones, it isn't at all noon by the clock always.

This thread was really created as a standalone entity as there is no facility out there to absorb the insight and certainly not the level of intelligence in this forum where the reasoning is enjoyed and expanded upon. Lots to work out including this topic, again, for those who can enjoy the reasoning.

The polar day/night cycle is almost a mirror of the daily day/night cycle in a having one sunrise/noon/sunset/midnight which are more familiar to observers as an expanded version of Solstices and Equinoxes broken into hemispherical terms (polar dawn, polar noon ect).

There is no such thing as meteorological noon as it is an extraneous concept, temperatures rise lag the event where a location is midway either side of the circle of illumination (in geocentric terms it is the Sun crossing the observer's meridian) . It is simply taken for granted that temperatures rise past noon and slowly fall towards sunset and likewise polar noon is the equivalent of daily noon and midsummer where temperatures will continue to rise at the North pole until a few months later when they begin to fall. The area of constant sunlight with the North pole at the center has a bearing on this as the surface area begins to decline post June Solstice.

People who created meteorological summer and therefore putting it in competition with polar noon wouldn't have the capabilities to discuss things like climate modelling ,Arctic sea ice evolution and its cause, the principle rotations behind the seasons and all the other topics that go begging for reasonable people.

With polar noon in just little over a week and the maximum area at the North pole in constant solar radiation, it is time to explore how that circle expands and contracts over the course of an orbit and how the degree of inclination influences how fast or how slow that circle expands and contracts for such is planetary climate.

A person from Sweden who is unable to recognize the present expanding circumference of area with the North pole at the center where the Sun is constantly in view !. The distance between the North pole and the circle of illumination is now increasing ever so slowly hence the maximum circumference known as the Arctic circle and its Southern equivalent.

I worked on Melkøya island about a decade ago within the Arctic circle and certainly came to appreciate the way most of humanity responds to the rhythms of daily rotation and the day/night cycle and how difficult it is to adjust to constant sunlight.
