I am trying to find out the southern - most star with a proper name. So far I have Miaplacidus (Beta carinae) at J2000 of -69:43:03.2. Just north of it is Atria (Alpha T Australis) at J2000 of -69:01:40.1.
But I don't know if this is the end of the matter. There may be a named star lurking around the pole, its proper name long since fallen from use. Maybe named by some 18th century type?
Any advances on Miaplacidus???
