Scientific paper
Long-term light curves of the cataclysmic variable BKLyn=PG0917+342 from the Indiana Automated CCD photometric telescope (`RoboScope') and the Harvard College Observatory plate achive reveal no dwarf nova outbursts. Two radial velocity studies show its orbital period to be 107.97+/-0.07 min, confirming that it does have an orbital period shorter than the period gap for cataclysmic variables. Whether this is the first nova-like variable below the period gap or a dwarf nova with rare outbursts resembling WZSge is still unclear, however.
