It's even Messier than that!

<<The supernova was noted on July 4, 1054 A.D. by Chinese astronomers as a new or "guest star," and was about four times brighter than Venus, or about mag -6. According to the records, it was visible in daylight for 23 days, and 653 days to the naked eye in the night sky. It was probably also recorded by Anasazi Indian artists (in present-day Arizona and New Mexico), as findings in Navaho Canyon and White Mesa (both Arizona) as well as in the Chaco Canyon National Park (New Mexico) indicate; there's a review of the research on the Chaco Canyon Anasazi art online. In addition, Ralph R. Robbins of the University of Texas has found Mimbres Indian art from New Mexico, possibly depicting the supernova.>>

<<Every 18 1/2 years, the moon and earth return to approximately the same positions they had on July 4, 1054. If you happen to be in Peñasco Blanco around this time, situate yourself with a telescope under that shelf of West Mesa and look up in the sky. Wait until the moon is in a position pointed to by the fingers of the hand. And then use the diagram under the shelf to position your telescope at the large star in the petrograph. Look in your telescope, and you will see the Crab Nebula.>>
