Flat Earth Projects / Wiki Update Request - Southern Celestial Rotation
« on: January 05, 2021, 07:11:43 PM »
The https://wiki.tfes.org/Southern_Celestial_Rotation page has the following question and answer
Can we discuss a better answer? During the weeks surrounding the solstice in December this answer is true and works great, but in June the hours of darkness on the southern coast of Australia and South America are lengthened to the point that they do indeed have simultaneous viewing of the same stars. I used https://www.timeanddate.com/sun/south-africa/cape-town to compare the nautical twilight hours in Cape Town, South Africa to Melbourne, Australia on June 14th, 2020 and there are over 3 hours of simultaneous night time viewing at those locations.
What would be a better answer to this question?

Q. How can two people on opposite sides of the earth in Australia and South America both see the same South Pole Stars simultaneously?
A. Since those areas are many hours apart from each other, when it is night or dusk for one area it is likely day or dawn for the other. It is questioned whether it is the case that those observers see the same stars simultaneously. Due to the time difference it may be that they see the stars alternately.
