At http://news.discovery.com March 30th … the second pharaoh of dynasty 6, Userkare, does not have a pyramid assigned to him at the present time. However, Guido Magli, a professor of archaeoastronomy in Milan has published evidence in the journal Mediterranean Archaeology and Archaeometry that claims he is able to pinpoint where exactly it should be. Diagonal axes governed the pyramids of Giza, Abirsir and Saqqara – created NE to SW (like the dominant alignment at Stonehenge). However, dynasty 6 pharaohs sometimes had variations from N to S (along the Meridian) and Magli has used this fact to locate the pyramid of Userkare (but only on the map).
