Moonlight at the South pole

There is a day/night cycle provided by the reflected light of the moon within the polar day/night cycle provided by the orbital surface rotation.

In a few weeks it will return to darkness once more for the last time as polar dawn begins to appear at the South pole with the Sun appearing for the first time since March.

This is all going to be expanded on and worked out in detail.

Thank you for posting another video showing how the pole rotates.

I think you belong with those who imagine astronomy is a magnification hobby and speak in terms of what is above and below the local horizon. Anything else is assigned to the empirical theorists who are currently running out of things to say having successfully convinced the wider population that you need to be a mathematician to understand existence, of course, the price is that nobody pays attention anymore.

Given a chance people will be drawn to astronomical events like transits and eclipses as a means to become more involved with motions occurring in the celestial arena, not the whirling celestial sphere which occupies the magnification/identification crowd but the slow and incremental changes which can now be presented in time lapse, sequential imaging and in a manageable format.

The North and South surface points don't rotate as a function of the Earth's orbital motion no more than your location rotates at the speed experienced by those who live at the surface at the Equator. The polar points do rotate to the central Sun as a function of the Earth's orbital motion through space and indeed the entire surface also participates in this wonderful orbital surface rotation which we experience as the seasons when it combines with daily rotation.

All is calm at the South pole presently as the moon continues its orbit so when one of the space agencies from any of the planet's nations decides to put a telescope on the moon, they will see the North and South poles traverse the fully illuminated face of our home planet in turn depending on where the Earth is in its orbit around the Sun. This is not a taunt but a certainty.

I am getting so careless these days - the North and South poles don't rotate to the Sun as a function of daily rotation but they do rotate to the Sun as a function of the planet's orbital motion.

It is enchanting to see the reflected light of the lunar day/night cycle within the polar day/night cycle but this insight won't appeal to brutes or who think astronomy is only a hobby for a few hours at night.

This sort of thing I cannot really find amusing.

As the holder of an M. Sc. degree in Physics, I have taken first-year Calculus,
a second-year course in differential equations, and other mathematical courses,
and I am well aware of the usefulness of certain branches of mathematics -
specifically, those in the area of analysis - in the study and control of the
physical world.

Thus, I _know_ from direct and personal experience that the use of mathematics
by scientists is not an imposture perpetrated on an innocent, trusting, and
gullible populace. The notion, indeed, is ludicrous.

A claim such as this is only possible through ignorance.

And it requires more than just ignorance to say such things as you did.

It requires the attitude that says: "Since I don't understand this, it isn't
because I'm not as smart in some ways as other people, or even because I
haven't taken the time or made the effort to learn about it - no, it must be
all worthless mumbo-jumbo!"

And you should know where that attitude comes from. It comes from the sin of
pride.

That depends on what you mean by "rotate". The North and South poles don't
_move_ as a result of daily rotation - because they're on the axis that pivots
it - but the orientation in relation to the Sun of a person standing at the
South Pole would change in a cycle of 24 hours.

Of course, one could say that a mathematical point, having no internal
structure, can't really rotate.

The reflected light of a lunar day/night cycle within the polar day/night cycle doesn't require anything more than a brief consideration of the moon's motion around the Earth each month and it really is enchanting -

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

To see something happening in real time is truly special and an indication of whether people are comfortable living with 21st century imaging and the conclusions and insights drawn from these observations.

On any given day there are motions to account for and especially the motion going on beneath the feet of humanity and separately the planet's orbital motion through space and around the Sun. In this clear perceptual air where experiences of the day/night cycle and the seasonal cycle make sense, the insights start to flow once more and break up the self-imposed celestial sphere shell humanity acquired from people a number of centuries ago.

A video showing how the South Pole rotates in a 24 hour day.

The only valid view at the South pole is that the Sun comes into view at the March Equinox and is absent from view after the September Equinox representing the distinct polar day/night cycle and the surface rotation behind it..

The insight is for those who have already accepted that the daily rotational speeds diminish from a maximum at the Equator to zero at the poles with the speeds contained within the 24 hour system and Lat/Long system which celestial sphere cultists seem intent on ignoring.

A little over a mile from the North and South poles and the daily rotational speed at the surface is 1/4 mile per hour while, as a function of its orbital motion, the same location turns in a circle to the central Sun at an average rate of 30 miles per day with greater or lesser values depending on the orbital speed of the Earth. This variation shows up at lower latitudes where it combines with constant daily rotation.

It doesn't matter to me what qualification a person has, common sense dictates that the ground beneath your feet has a specific daily rotational speed and that changes as you move towards the Equator or towards the North and South poles in your respective hemisphere. The maximum speed any person experiences as a function of daily rotation is 1037.5 miles per hour at the Equator insofar as the geographical separation represented by that value is 15 degrees of longitude and 1 hour's timekeeping difference.

Thank you for the time lapse of the moon as it makes a circuit of the Earth and don't forget that the major insight is the continuous reflected light as the moon passes across the polar surface in its monthly orbit of the Earth. Do not, I repeat, do not bundle lunar motion with circumpolar motion otherwise it wastes an entirely wonderful perspective of the monthly lunar orbit and the unique view at the poles.
