Abstract: The Berlin Exoplanet Search Telescope II BEST II is a small widefield-of-view photometric survey telescope system located at the ObservatorioCerro Armazones, Chile. The high duty cycle combined with excellent observingconditions and millimagnitude photometric precision makes this instrumentsuitable for ground based support observations for the CoRoT space mission.Photometric data of the CoRoT LRa02 target field collected between November2008 and March 2009 were analysed for stellar variability. The presentedresults will help in the future analysis of the CoRoT data, particularly inadditional science programs related to variable stars. BEST II observesselected CoRoT target fields ahead of the space mission. The photometric dataacquired are searched for stellar variability, periodic variable stars areidentified with time series analysis of the obtained stellar light curves. Weobtained the light curves of 104335 stars in the CoRoT LRa02 field over 41nights. Variability was detected in light curves of 3726 stars of which 350showed a regular period. These stars are, with the exception of 5 previouslyknown variable stars, new discoveries.
