摘要

The statistical properties of sunspot and active regions (plages) distributions obtained from the automated Solar Feature Catalogues (SFC, http://solar.inf.brad.ac.uk) for 1996-2005 and their relation to H{sub}α flare occurrences are presented. The average monthly flare occurrences during the cycle 23 correlate rather closely with but do not follow exacly the sunspot area variations. The temporal distribution of solar flare occurrences at different latitudes in the Northern and Southern hemispheres reveal strong asymmetry reflected in periodic domination either one or another hemisphere that follows closely those of the plage and sunspot areas. The latitudinal distribution of flare occurrences in the whole period reveal a well defined maximum at 20° in the Northern hemisphere that is likely to be associated with the domination of the Northern hemisphere in the sunspot formation during the solar amximum years. The longitudinal distributions of flare occurrences in the cycle 23 averaged in latitudes over a year reveal a persistend longitude of 200° with small fluctuations about ±10° with the period of about 1-1.5 years. Possible implications on solar dynamo models of the detected latitudinal and logitudinal asymmetries in the sunspot, active region and flare occurrences are discussed.
