The image on the left of the f68r fold-out shows what is possibly the sun over the moon, and stars. Again, there are no geometric markers on the page but the eyes of the sun and moon have been used as markers. The sun appears to look in a single direction and the moon in two. If the same pattern is applied on a star map on the day the supernova is said to have been recorded, the 4th July 1054 at the time the sun is above the moon and in relation to the supernova rise/set times, this would place it around 4.40 PM local time at the point when the supernova is setting on the first day. At this time the sky is bright and only the sun and supernova would be visible as the moon has set. I propose the appearance of the moon on this page being different from the other moon faces is that it represents asset moon below the horizon. Some stars are shown of what would probably be found in the general area and as some things are below the horizon it would show calculated positions rather than observed positions, but the image is a general setting of the scene. Although one would not expect any correspondence to be accurate it does reflect the same overall pattern of the image eye markers. The horizontal marker running through the sun would also run through Procyon and this triangle of Moon, Sun and Alkaid or Ursa Major may have been used to calculate the position of SN 1572 in Cassiopeia, for comparison to SN 1054. If the true sky colour is turned off and the brightest stars shown. This becomes more apparent. The North Pole, the centre of the Chinese sky map, is also directly over Cassiopeia at this time. This assumes that the actual position of the Sun in the image has been displaced for the sake of symmetry on the folio.

Another view of the star map without true sky colour showing more clearly the actual positions of major stars and the planets.
