             abstract = "Using airglow data from an all-sky imager deployed at Sao Joao do 
                         Cariri (7.4 degrees S, 36.5 degrees W), the start times of 
                         equatorial plasma bubbles was studied in order to investigate the 
                         day-to-day variability of this phenomenon. Data from a period over 
                         10 years were analyzed from 2000 to 2010. Semimonthly oscillations 
                         were clearly observed in the start times of plasma bubbles from 
                         016300 airglow images during this period of observation, and four 
                         case studies (September 2003, September-October 2005, November 
                         2005 and January 2008) were chosen to show in detail this kind of 
                         modulation. Since the airglow measurements are not continuous in 
                         time, more than one cycle of oscillation in the start times of 
                         plasma bubbles cannot be observed from these data. Thus, data from 
                         a digisonde at Sao Luis (2.6 degrees S, 44.2 degrees W) in 
                         November 2005 were used to corroborate the results. 
                         Technical/climate issues did not allow one to observe the 
                         semimonthly oscillations simultaneously by the two instruments, 
                         but from October to November 2005 there was a predominance of this 
                         oscillation in the start times of the irregularities over Brazil. 
                         Besides, statistical analysis for the data in the whole period of 
                         observation has shown that the lunar tide, which has semimonthly 
                         variability, is likely the main forcing for the semimonthly 
                         oscillation in the start times of equatorial plasma bubbles. The 
                         presence of this oscillation can contribute to the day-to-day 
                         variability of equatorial plasma bubbles.",
