Within a couple of days winter season is started. This is the period that the sun's orbit at the sky is increasing again untill mid june. A way to capture this daily increase of the sun's orbit is by installing a pin hole camera with photopaper. The result you will get after 6 months is a solargraph. You can make this yourself by installing a regular 50 or 72cl can with photopaper outside for this period of six months.
DIY Solargraph and results can be seen on these pages of my blog. Good luck!
