When inquired by the Udaijin (Minister of the Right) Kanezane KUJO, Suehiro stated that when the similar phenomenon was observed in 1177, his deceased father ABE no Yasuchika said that it was a comet, but he objected to that; then his father asked Heaven to give them judgment by punishing the wrong one, and consequently, Suehiro fell seriously ill, thereby they confirmed that it was a comet -- therefore, it could be concluded that actual movement of stars did not matter (the entry of "Gyokuyo" [the diary of Kanezane KUJO] for February 4, 991).
右大臣九条兼実の諮問を受けた季弘は、治承元年（1177年）にも同じようなことがあり、亡くなった父安倍泰親が彗星といい、自分がであるとしたので、父が天に判断を仰ぎ誤った方に天罰が下ることを祈請したところ、自分が重病になったので彗星だと判明した。従って実際の星の動きは問題ではないと唱えたという（『玉葉』正暦二年1月12日(旧暦)条）。
