The current paper is part of a series of papers describing the results of our stellar variability survey. The BEST is a small aperture telescope with a wide field of view (FOV). It is dedicated to searching for stellar variability within the target fields of the CoRoT space mission to aid in minimizing false-alarm rates and identify potential targets for additional science. The LRa1 field is CoRoT's second long run field located in the galactic anticenter direction. We observed the LRa1 stellar field on 23 nights between November and March 2005/2006. From 6099 stars marked as variable, 39 were classified as periodic variable stars and 27 of them are within the CoRoT FOV. We also confirmed the variability for four stars listed in the General Catalogue of Variable Stars (GCVS). Description: The LRa1 was observed between 2005 November 21 and 2006 March 6. The total time baseline of our observations spreads over 104.937days. File Summary:

Note (2): Magnitudes correspond to a wide R filter (650-800nm), calibrated against the USNO-A2 catalog (I/252) only. Note (3): Variability class as follows: CEP = Cepheid DSCT = Variable of the Delta Scuti type EA = Algol (Beta Persei)-type eclipsing system EB = Beta Lyrae-type eclipsing system ELL = Rotating ellipsoidal variable EW = W Ursae Majoris-type eclipsing variable
