Abstract
Candidate variable stars in the publicly available data of the Optical Gravitational Lensing Experiment (OGLE) project were identified by data mining the galactic disk photometry database for entries that matched the following criteria: mean i-magnitude between 8 and 14 and standard deviation of i- magnitude between 0.5 and 1.0. Ten previously uncatalogued Mira variable stars have been identified, with only stars not listed in the International Variable Star Index (VSX) at the time of submission being included.
