Name origin

The Latin-Arabic name "Alfecca meridiana" is mentioned in Allen (1899, 173). There, it is attributed to "Reduan" (sic!) = Ali bin Radwan's commentary to his Tetrabiblos translation (10th century). Arabic نير الفكّة nayyir al-fakka "the bright (star) of the broken (dish)" in analogy to the Arabic term for CrB. WGSN chose only the second (Latin) term: "Meridiana", the southern (one of the two Alfeccas).
