It's been a while since I looked at it.
It is also known as DUN 31 after its discoverer.
Lovely contrast with stellar spectral types G8 and A0.
Latest GAIA parallax data from SIMBAD would put the stars at very similar distances. So, they may actually be a gravitational pair rather than just a line of sight coincidence.
SIMBAD also classifies it as V Pup but this appears to be an error as there is another V Pup in the database.
