             abstract = "We have constructed a time series of the number of coronal mass 
                         ejections (CMEs) observed by SOHO/LASCO during solar cycle 23. 
                         Using spectral analysis techniques (the maximum entropy method and 
                         wavelet analysis) we found short-period (<\ one year) 
                         semiperiodic activity. Among others, we found interesting 
                         periodicities at 193, 36, 28, and 25 days. We discuss the 
                         implications of such short-period activity in terms of the 
                         emergence and escape of magnetic flux from the convection zone, 
                         through the low solar atmosphere (where these periodicities have 
                         been found for numerous activity parameters), toward 
                         interplanetary space. This analysis shows that CMEs remove the 
                         magnetic flux in a quasiperiodic process in a way similar to that 
                         of magnetic flux emergence and other solar eruptive activity.",
