Potential alignment of the stone

What is a seasonal sundial

 

This is a movie showing where the sun rises in each of the months.

In the winter months it is on the south-east side.

In the summer it is on the north-east side.

The earths axis causes the different places the sun rises.

 

The axis of the earth also creates the different height the sun reaches in the sky throughout the year. For example; in the summer the sun gets to its highest point in the sky, however in winter the sun stays low on the horizen.

 

In the summer the north facing side of the stone is always illuminated by the sun when it rises and sets. This is because the sun rises in a more northern position on the horizen. In the winter the northern side is never illuminated becasue the sun rises and sets towards the south.

 

Also the angle of the stone slopes from north up to south at an angle of about 60 degrees. Also when it is the middle of summer the sun will be at its highest point of about 60 degrees. This means for a couple of days in the middle of summer the whole north side will be completely illuminated all day.

Ashleigh: "I watched the video on the first page and I think I understood the general idea however there are some parts I didn’t understand. For example I didn’t completely follow the middle part about the summer and winter halves and north and south sides. However I find it much easier to pick up thing if I’m told in person and I’m sure it won’t take long for me to catch up."
Soooooo, this is the ideal place to present how the light and shadow will illuminate the standing stone throughout the seasons here :)
