[en] Light curves of four transits of the extrasolar planetary system WASP-2 are presented, obtained with substantial telescope defocussing in order to improve the photometric precision of the observations. Three of the datasets were obtained using the Danish 1.5m telescope, DFOSC camera and R filter at ESO La Silla in 2010. One of these datasets was affected by cloud, so was not included in our analysis but is archived with the rest of the data in case it is useful to others. The fourth dataset was obtained with the Loiano 1.52m telescope, BFOSC camera and a Gunn r filter. We also include a datafile containing the times of transit midpoint from our own data and from other sources.
