高倉院 治承五年 六月廿五日 庚午 戌時 客星見北方 近王良 守伝舎星
In the reign-period of Takakura-In, June 25th, 5th year of Jisyou (= August 7th, 1181), a guest star appeared in northern sky at 20:00. It was near to the star of “Oh-Ryo” (= real person’s name of ancient China) and “Densya”.
王良 (Oh-Ryo)Cassiopeiaβ
伝舎 (Densya) = Camelopardalis

In the reign-period of Goreizei-In, after the middle of April, 2nd year of Tenki (= May-June, 1054), a guest star appeared
nearby “Shi” and “Shin” (= Orion) in eastern sky at 2:00. It shined near to the star of “Tenkan”, and its size was comparable to Jupiter.
