There seems to be a great deal of confusion about the sun during the Spring & fall months. The equinox dates are Sept 23rd & Mar 21st.
Despite the axis shift which depending on the year, has extended the tropic of cancer 850-2000 miles (depending on the year) north of its normal position in mid Mexico on June 21st the summer solstice and 850-2000 miles south of the tropic of Capricorn during the winter solstice on Dec 21st… that means the equator is still the midpoint despite the axis shift. The amount of the shift will alter the sun position equally north in the Summer and to its opposite & equal position to the south in December. This is due to the way we orbit the sun at a tilt. Even with an exaggerated or increased tilt, the sun is the same distance too far north during June as it is the same equal distances too far south in December.
This means the equator is still midpoint between the two tropics. This also means that the sun is directly over the equator on March 21st and September 23rd. This was also the same midpoint when the axis was normal. So no matter how much the axis shifts, it will always measure the same over the equator in March and Sept. equinoxes. During the spring & fall months the sun travels between the tropics of Capricorn & Cancer crossing the equator on the equinox dates I mentioned above. It performed this journey the same way before 2000 Y2K or now. And still does so whether the axis tilt & tropic lines were normal or whether each tropic line had shifted 850-2000 miles beyond their normal tropic lines with the increased axis shifts & tilt. The difference before Y2K was the shorter distance the sun traveled between the two tropic lines. After the axis shift that distance of travel increased. For instance, when the earth shifted 850 miles to the north, the sun traveled an extra 1700 miles between the 2 increased tropic lines but was always over the equator on the spring & fall equinoxes.
So it does not mean a thing if you measure the sun position or axis now. Because the sun during the spring & fall equinoxes will be the same no matter what the axis tilt is. So if you go outside & measure the sun position & shadows during the spring & fall months it means nothing. This is because of the way earth orbits the sun at a tilt. This was taught in 3rd grade science.
The only 2 dates which are meaningful in measuring the sun position are June 21st for those of us who live in the northern hemisphere and December 21st for those of you who live in the southern hemisphere.
I may have to adjust the solstice measuring dates because our position has altered from what it was.
This June, we need to take measurements on both June 20th & 21st.
December is still the 21st. Both equinoxes occur a day early in 2016.
In 2017 & 2018 both solstices will again occur on June 21st & Dec 21st… if we can believe the sources.
One other item concerns comparing sun position over certain spans of years. Most of the axis shifts occurred after 2003. Before 2007. Between 2007 & 2013 only a couple small shifts occurred. For several years it remained at the same position. So if you compared the wrong years, there were no changes at all. Then then was the huge increase between 2013 & 2014. Then the significant reversal between 2014 and 2015,
I’ve measured the changes every year since 2006 but I caution everyone to be careful not to compare the wrong months or wrong year. Otherwise you will make erroneous comparisons. The earth does not shift every year. Nor can you see the shifted sun position during the spring & fall months. There have been several people jumping the gun who are trying to compare the sun position this month, so it appears I need to explain why it cannot be done in spring or fall. Only the solstice dates can provide the info we need.
Only June 21st for the Northern Hemisphere annual measurement. This year will be June 20th & 21st. Then Dec 21st for those in the southern hemisphere to measure.
These are the two days of the year when the sun is the farthest north and farthest south, indicating when it is directly over the tropics of Cancer & Capricorn. And how far beyond those lines it has traveled due to the axis shift.
