2nd century BC Han comet record

• ... that historical comet observations in China (example pictured) as far back as 12 BC have been used to study changes in brightness of Halley's Comet? Source: Stepenson and Yau, "Oriental tales of Halley's Comet", New Scientist, p. 32, 27 September 1984.

• Comment: This was a X5 expansion as well as GA, but I forgot to submit it at the time. Actually, it is a X infinite expansion as the original page had exactly zero qualifying text.

• Recent GA. The article and hooks are referenced. AGF because of the offline sources. No copyright or neutrality issue detected. QPQ is done. Good to go.--KAVEBEAR (talk) 09:46, 5 February 2017 (UTC)
