A guest star appears in Taurus and is recorded in East Asia

node

Chinese court astronomers of the Song dynasty recorded a new star near the southern horn of Taurus, bright enough to be seen in daylight for a period usually given as about twenty-three days, and visible at night for roughly two years. Japanese records refer to the same object. The material was assembled and connected to the Crab Nebula by the sinologist J. J. L. Duyvendak in 1942. The date of first sighting is not settled: 4 July 1054 is the conventional value, but some records and later analyses point to an earlier appearance, and the discrepancy is a genuine problem in the source criticism rather than a rounding difference.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.

  26. Supports the recording of a guest star in Taurus in 1054 and its identification with the Crab Nebula. The conventional first-sighting date of 4 July 1054 is contested in the source-critical literature and is presented here as disputed rather than settled. None of the reviews was fetched.
