Statistical properties of sunspot, active region distributions and flare occurrences in the cycle 23 as detected from the Solar Feature Catalogues The statistical properties of sunspot and active regions (plages) distributions and their relation to flare distributions are presented for 1996-2005 from the automated Solar Feature Catalogues from the SOHO and Meudon Observatories (SFC, http://solar.inf.brad.ac.uk). Cross-correlation analysis is carried out between flare sizes, locations, significance and active region/sunspot parameters including magnetic field extracted in SFC. Sunspot and plage area distributions reveals a strong North-South asymmetry of about 0.2 and the period of about 7-8 years for sunspots and of 0.5 and period of 9 years for plages with both asymmetries decreasing towards the next cycle minimum. The temporal distribution of solar flare occurrences in Northern and Southern hemispheres, at different latitudes and longitudes are compared with those of plage and sunspot areas and LOS magnetic fields. The application of these results to the solar activity forecast is discussed.
