We introduce three new variable stars discovered during asteroid photometry. This includes two new eclipsing binary stars, GSC 1393-1461 (P=0.311145d) and GSC 2449-0654 (P=0.343802d), and one new flare star: GSC 5604-0255, which had a 35%±2% intensity increase with a decay half-life of 20±1 minutes. This paper presents light curves along with basic models and analysis of the data.
