Summary:
    We describe photometry of 907 galaxies brighter than b26.25=20.5 in a
    1.83X1.83 area centred on the southern cluster Sersic 129-01 in the u,
    b, r and i bands. The slopes and zero-points of the colour-absolute
    magnitude diagrams agree well with other clusters including Coma and
    the rich cluster Shapley 8 suggesting they are independent of cluster
    environment. The (u-b) against (b-i) diagram distinguishes well
    between morphological types. The reddening we obtain by a number of
    methods disagrees with that of Griersmith (1982AJ.....87..462G). The
    L-{sigma{ relation has a similar form to other clusters and when
    combined with data for Virgo leads to a relative distance modulus
    which agrees with that from Griersmith's comparison of
    colour-magnitude diagrams only on the assumption of E(B-V)=0.15 in
    front of the cluster and a high value of H0. A mass of
    7.4x1013M☉ is found for the elliptical dominated component of
    the cluster and (M/L)b=59.
