We examine simultaneous X-ray and UV light curves from multi-epoch 8 day XMMNewton observations of the narrow line Seyfert 1 galaxy 1H 0707-495. Thesimultaneous observations reveal that both X-ray and UV emission are variableand that the amplitude of the X-ray variations is significantly greater thanthat of the UV variations in both epochs. Using a discrete correlation function(DCF) the X-ray and UV light curves were examined for correlation on timescalesup to 7.0 d. Low significance (~ 95 percent confidence) correlations with theUV leading the X-ray variations are observed. The lack of a significantcorrelation between the UV and X-ray bands seems consistent with the X-raysource being centrally compact and dominated by light bending close to theblack hole. In addition, multi-band X-ray light curves were examined forcorrelations on similar timescales. Highly significant (> 99.9 per centconfidence) correlations were observed at zero lag consistent with previousstudies of this AGN.
