SuperWASP-N extrasolar planet candidates between 18 < RA < 21 h

The SuperWASP-I (Wide Angle Search for Planets-I) instrument observed 6.7 million stars between 8 and 15 mag from La Palma during the 2004 May-September season. Our transithunting algorithm selected 11 626 objects from the 184 442 stars within the RA (right ascension) range 18-21 h. We describe our thorough selection procedure whereby catalogue information is exploited along with careful study of the SuperWASP data to filter out, as far as possible, transit mimics.We have identified 35 candidates which we recommend for follow-up observations.
