Solar magnetic synoptic charts obtained by NSO/Kitt Peak and SOHO/MDI are analyzed in order to study the appearance of bipolar magnetic regions (BMRs) during solar minima. We find that the emergence of long-lived BMRs have three typical features. (1) The emergence rate of BMRs in the new cycle increases about 3 times faster than the rate of the ol…
