α Arae

Alpha Arae is found two binocular fields due south of theta Scorpii: binoculars.

To the naked eye, and even in telescopes, alpha and beta Arae appear to have the same brightness at 2.8 magnitude, but most catalogues record that alpha is actually 0.01 less bright. However the latest figures from the Washington Double Star Catalgue put alpha's magnitude at 2.79; as beta has a magnitude of 2.85 alpha can now claim to be just a bit brighter.

Alpha Arae is a wide binary (HJ4955) with a very faint companion: 2.79, 11.1; 168 and separation 49.7".

Between the two is the star cluster 6397, while 6193 is west of alpha three binocular fields. Click on these two on the map.
