Fellow Shadow Watchers,
Does anyone have a jpeg of the small stainless steel
polar dial seen at Royal Holloway College during the BSS Conference? It had
45° 'wings' to catch the early and late shadows and a solid black 'slate'
gnomon.On both occasions we passed it I had no camera with me. Hope someone can help Tony Moss --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
