Equinox
The Sun is getting ready to Set.
The Sun is closer to setting and the window of light will disappear out the window
The Sun is coming through the closer window and casting the shadow on the far wall. When the Sunsets the light window disappears.
The nearly Full Moon near Equinox Sunset
Just minutes before the light disappears.
Solstice
Solstice 2008 Ceremonial Sunrise...nearly complete...
Solstice Sunrise and the window of light begins to track down the wall.
The Sun is moving further down the wall
The window of light now sitting on the step
Dec Solstice 2008 with Window of light now on the floor of the circle
The Sun Circle and Solstice Ceremony

Solstice 2006... Cayelin showing the light moving down the wall.

Now it is a little further down

and now the light is on the floor of the corner of the step and the floor of the circle

This light tracks all the way across the floor of the circle and at Sunset will move up the opposite wall and disappear.
