There are 4 stars near Hubble’s Star (V1), a Cepheid variable in M31. Is this Hubble’s constellation? Take a look at Jim Al Khalili’s The Beginning of the Universe on the BBC Channel 4, BBC iPlayer if you have not seen it. Take a look at 8 minutes in. The programme was shown tonight, so perhaps this prompted your posting.
V1 at RA 0.41 22.77 DEC 41. 9″ 35.08 on ESA website. It would make sense if a group of stars near the variable was labelled Constellation 1 for identification purposes, but that doesn’t prove anything, of course. Perhaps Constellation 1 is somewhere else.
