Text #26Cometography: A Catalog of Comets. Series: Cometography. Vol. 1 .
Fragments of Babylonian cuneiform tablet BMA 45731 mention a comet seen on -156 October 19 and November 15. Unfortunately, no other details are available.
The Han shu (100) is the only ancient Chinese text to mention this object. It says a “sparkling star” was seen “in the western quarter of the sky” sometime during the lunar month of -156 October 8 to November 5. The text continues by noting that its “trunk laid straight across the Wei [ε, ζ, η, θ, ι, κ, λ, and μ Scorpii] and the Chi [γ, δ, ε, and η Sagitarii], and its end pointed to the Hsy [α Equulei and β Aquarii] and Wei [ε and θ Pegasi, and α Aquarii].” The object was over 10 degrees long and “reached the Milky Way.” It disappeared on the 16th day.
Full moon: October 15
