  In this paper, we investigate the inhomogeneous spatial distribution of solar
faculae. The focus is on the latitudinal and longitudinal distributions of
these highly localised features covering ubiquitously the solar surface. The
statistical analysis is based on white light observations of the Solar and
Heliospheric Observatory (SOHO) and Solar Dynamics Observatory (SDO) between
1996 and 2014. We found that the fine structure of the latitudinal distribution
of faculae displays a quasi-biennial oscillatory pattern. Furthermore, the
longitudinal distribution of photospheric solar faculae does not show
homogeneous behaviour either. In particular, the non-axisymmetric behaviour of
these events show similar properties as that of the active longitude (AL) found
in the distribution of sunspots. Our results, preliminary though, may provide a
valuable observational constrain for developing the next-generation solar
dynamo model.
