I investigated the historical records written about the supernova that appeared in 1006.I found 24 of them in eight countries and regions. Comparing these historical documents show differences in the colors, shapes, and period of appearance. In "Meigetsuki ", the color was recorded as red, on the other hand, blue and white in "Ichidaiyouki", yellow in "Song Huiyao Jigao", and dark green in "healer's book". The colors recorded were not the same. Although the shape is like a dot due to the distance between SN1006 and us, the “Song Shi” describes it as looking like a half-moon. The period of appearance is summarized by country or region:in Japan, and many other countries, it was three or four months. But in China, it was said to have been visible for several years. I tried to find out the reason why these differences have occurred via scientific perspective and experiments.
