Abstract:
    Recent wide field photometric surveys, which target a specific field
    for long durations, are ideal for studying both long- and short-period
    stellar variability. Here, we report on 75 variable stars detected
    during the observations of a field in Pegasus using the Wide Angle
    Search for Planets Prototype (WASP0) instrument, 73 of which are new
    discoveries. The variables detected include 16 δ Scuti stars, 34
    eclipsing binaries, 3 BY Draconis stars and 4 RR Lyraes. We estimate
    that the fraction of stars in the field brighter than V∼13.5
    exhibiting variable behaviour with an amplitude greater than 0.6% rms
    is ∼0.4%. These results are compared with other wide field stellar
    variability surveys, and implications for detecting transits due to
    extra-solar planets are discussed.

Description:
    The first observing run of WASP0 took place on La Palma, Canary
    Islands, during 2000 June 20 to 2000 August 20.

Note (1): The instrument uses a clear filter which has a slightly higher
          red transmission than blue.
Note (2): Variables for which there is an associated question mark have
          a small uncertainty regarding the classification.
     Variables for which a suitable classification could not be assigned
     are designated as unknown (U).
