These sky patrol data are a powerful resource for studies of astrophysical transients. As a demonstration project, we present first results of a search for periodic variable stars derived from ROTSE-I observations. Variable identification, period determination, and type classification are conducted via automatic algorithms. In a set of nine ROTSE-I sky patrol fields covering roughly 2000 deg^2^, we identify 1781 periodic variable stars with mean magnitudes between m_v_ = 10.0 and m_v_ = 15.5. About 90% of these objects are newly identified as variable. Examples of many familiar types are presented. All classifications for this study have been manually confirmed. The selection criteria for this analysis have been conservatively defined and are known to be biased against some variable classes. This preliminary study includes only 5.6% of the total ROTSE-I sky coverage, suggesting that the full ROTSE-I variable catalog will include more than 32,000 periodic variable stars. 2000AJ....119.1901A https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/119/1901 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to J/AJ/106/2429 : Behlen Obs. variables stars survey (Schmidt+, 1993) J/AJ/112/2769 : Behlen Observatory Survey.
