Syu and All -



Nice diagram of a way to directly observe the movement of the Sun! I

tried this one a few years ago and found something that works really

good for the clear half globe. In our area of the world there is a

company that sells ladies stockings in plastic containers shaped like

eggs. Some come with 1/2 clear. They are about 6 or 8 cm. in diameter.

For something to make a shadow with inside the dome we took a tiny

plastic action play figure (REALLY tiny!) and glued it to a piece of

notepad board. Then we glued the 1/2 egg to the board. After getting the

dome oriented (N/S) we made a mark on it once an hour where the top of

the figure's shadow met our pen-tip's shadow. 



You could measure your latitude using this info (where the shadow was at

local noon - when the Sun is due south) and compensating for the Sun's

annual changes in latitude using something called an analema. 



Clear Skies,

Kye Ewing
