Abstract
VLT images in the V-band are used to make light curves of transits of candidate OGLE planets. The data for some of the targets are complemented with NTT K-band images. Using difference image photometry, we are able to achieve milli-mag errors in the individual datapoints. Here we discuss the observations, and data reductions. We also present the preliminary results for OGLE-TR-109, arguing that it is likely to be a new transiting planet....
