Abstract
In this work a wavelet spectral study of a time series of brightest fireballs is presented. The wavelet analysis shows that are two solar periodicities around 27 and 13.5 days. These periodicities have been associated to Carrington rotation and lunar motions and indicate that both Solar and Lunar rotations could have an influence on the brightest fireballs fall on Earth. A third periodicity around 2.5 days was also identified in almost all spectra but it could be a harmonic of those periods.
