Designation: HR 4540

Name origin (IAU): From a contraction of the pre-Islamic Arabian name zawiyat al-'awwa', "the Angle of al-'awwa'," for γ Vir. Wrongly transferred to β Vir in recent times. The stars β, η, γ, and ε Vir marked the pre-Islamic Arabian lunar mansion al-'awwa' (with γ in its "angle"), but the meaning of al-'awwa' is unknown.

Constellation

Light from this object takes about 36 years to reach Earth — the light you see tonight left around AD 1990 (official distance ÷ speed of light).
At magnitude 3.6 it is bright enough for the naked eye (limit about 6) — look from somewhere dark.
Declination 1.8° — it rises above the horizon in Seoul (37.6° N), so it is visible from Korea in the right season.
