We have searched the K2 campaign 0 data for lightcurve variations associated with stellar variability. The results of this search are presented as a catalogue, giving the identiers of nearly 2500 variable stars in the dataset. We list the detected range of the variation, periodicity if relevant and semiamplitude. Lightcurves are classied into strictly periodic, quasi-periodic and aperiodic groups. We do not attempt to identify the source of variability, which may arise from pulsation or stellar activity. However, we cross match the objects against variable star related guest observer proposals, specifying the variable type in many cases. At present eclipsing binary stars are not included. Future releases will address each K2 eld as it is made available, and may be improved to include more detailed catalogue information and to provide detrended object lightcurves.
