Checked the Yuan and Ming catalogue
Extracted the Hayakawa 2017 catalogue. Found an aurora candidate on 9 February 1261 with three records, matching the proposed 1261 radiocarbon rise. Nothing at all for 1277 to 1282, so the 1279 candidate has no Chinese witness.

Korea's violet glow of 25 October 1279 falls in the window for the 1279 to 1280 radiocarbon jump, and the main paper missed it
This step led us to
