−	Accepting the main clue as a foundation, the next clue is Bosch's third monologue, which states, "The nebula is the remnant of a supernova thousands if not billions of light years from Earth; and I wonder now if our ancestors witnessed the death of this star erupting over an Egyptian landscape, blazing with the brilliance of four hundred million suns." This gives an approximate estimate for the distance and apparent magnitude of the supernova.

−	SN 1006 was about as bright as five billion suns, while SN 1054 was about as bright as 1.25 billion suns. These figures are within approximately one order of magnitude of Bosch's estimate. Furthermore, taking the speed of light into account, SN 1006 erupted in 6,094 B.C., while SN 1054 erupted in 5,246 B.C. These dates are within only 1,000 years (for SN 1054, 500 years) of the Vasudan estimate. Both estimates are surprisingly accurate.
