The Tip of the Elbow (ibrat al-mirfaq)
The Tip of the Elbow is part of the Henna-Dyed Hand (al-kaf al-khadib) of Thuraya, a brilliant star cluster that was anthropomorphized as a female figure. One of two Hands, the Henna-Dyed Hand is longer than the Amputated Hand (al-kaf al-jadhma’) and features several well-defined elements.
A single dim star located very close to the Elbow of Thuraya, likely identified as either ψ PER or σ PER.
ψ PER, blue-white star, magnitude 4.38
σ PER, orange star, magnitude 4.35
The Tip of the Elbow sets about the time that the Brand (al-haq’a) sets. Ibn Qutayba (d. 879 CE) reported that the Brand was said to set on the morning of December 9. On account of the precession of the equinoxes, today we can expect to observe the Tip of the Elbow setting in early January and rising in the middle of April, as seen from the latitude of Tucson. (See How to Observe on the About page for more on this topic.)
The Tip of the Elbow does not figure among the rain stars.
The Tip of the Elbow is not one of the lunar stations.
