英文摘要	We found a possible similar to 1 h quasi-periodic oscillation (QPO) in a similar to 55 ks X-ray observation of the narrow-line Seyfert 1 galaxy MCG-06-30-15 made with the XMM-Newton EPIC/pn detector in the energy range 0.3-10 keV. We identify a total modulation of similar to 16% in the light curve and find a similar or equal to 3670 s quasi-period using Lomb-Scargle periodogram (LSP) and weighted wavelet Z-transform (WWZ) techniques. Our analyses of eight light curves of MCG-06-30-15, indicated the possible presence of an oscillation during one of them. The LSP indicates a statistically significant (similar or equal to 3 sigma) QPO detection. A WWZ analysis shows that the signal at this possible roughly 3670 s period is present, and rather persistent, throughout the observation; however, a signal around 8735 s is more persistent. We briefly discuss models that can produce X-ray QPOs with such periods in narrow line Seyfert 1 galaxies, as both other claimed QPO detections in this class of AGN had very similar periods.
