We have performed photometric observations of nearly seven million stars with 8 < V < 15 with the SuperWASP-North instrument from La Palma between 2004 May to September. Fields in the right ascension range 17–18 h, yielding over 185 000 stars with sufficient quality data, have been searched for transits using a modified box least-squares (BLS) algorithm. We find a total of 58 initial transiting candidates which have high signal-to-noise ratio in the BLS, show multiple transit-like dips and have passed visual inspection. Analysis of the blending and the inferred planetary radii for these candidates leave, a total of seven transiting planet candidates which pass all the tests plus four which pass the majority. We discuss the derived parameters for these candidates and their properties and comment on the implications for future transit searches.
