I have watched the Sun's shadow make its trek from the solstice moments for many years. I have it marked and like to observe it as Earth's tilt reaches it's maximum point, from Summer to Winter and back. I used a heliodon to built a large structure (80 feet long/12 feet tall=roofline of my house) that gives me a long shadow line. It is not perfect, but reliable for my purposes. I have been observing this shadow-progression for the past 7 years and have the solstice shadows marked for record. Question: Is there someplace/website I can visit to see a real-time recording of the Sun's shadow this year, as compared to years previous? Thanks.
