The Spiral Galaxy in Ursa Major, NGC 3877 (= H I.201), type Sc, is best found from Chi Ursae Majoris, which is almost exactly 15 arc minutes north of the galaxy.
In Chinese astronomy, Alkafzah is called Tae Yang Show, "the Sun Governor"[1]. The name was possibly derived from the word 太陽守, Pinyin: Tàiyángshǒu, meaning Guard of the Sun, because this star is marking itself and stand alone in Guard of the Sun asterism, Purple Forbidden enclosure (see : Chinese constellation).
