These include 48 newly identified objects with periods <2x104s (∼0.23d), as well as the shortest period binary known with main sequence components (GSC2314-0530 = 1SWASP J022050.85+332047.6) and four other previously known W UMa stars (although the previously reported periods for two of these four are shown to be incorrect). The period distribution of main sequence contact binaries shows a sharp cut-off at a lower limit of around 0.22d, but until now, very few systems were known close to this limit. These new candidates will therefore be important for understanding the evolution of low mass stars and to allow investigation of the cause of the period cut-off. Description: The catalog contains the list of 53 candidate short period eclipsing binaries. The SuperWASP ID encodes the J2000 position of the star as 1SWASP Jhhmmss.ss±ddmmss.s. In the table we list the RA and Dec of each object extracted from the SuperWASP ID. We also list the orbital period in days, the peak magnitude of the object in the SuperWASP V-band, along with the depths (in magnitudes) of the primary and secondary minima. File Summary:
