Simulated night sky looking south from the location of the petroglyph at midnight on May 1, 1006. The horizon profile is a true representation of the site horizon, made from photographs taken at the site and placed correctly with respect to the stars and the direction of true south. The supernova appears just above the horizon near center; the constellation Scorpius grazes the horizon left of center. Credit: G.A.
