Hello, everyone, Slightly off-topic, but fun :
New Scientist magazine for 2008-10-04, page 46, features a solargraph - an image that shows the track of the sun's position over time - that was made using a pin-hole camera pointed at the Clifton Suspension Bridge in Bristol UK. The image was collected between the most recent winter and summer solstices. You can view the same image at http://www.newscientist.com/gallery/mg20026761900-solargraphs-show-half-a-year-of-sun/1 Click the image to flip through a series of 5 solargraphs that the artist has made available to New Scientist. http://www.solargraphy.com is a site dedicated to such images. Happy (Canadian) Thanksgiving! Steve --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
