Abstract

A search of the Harvard College Observatory plate collection has revealed four previously unknown outbursts of the cataclysmic variable V725 Aquilae, as well as a confirmation of an outburst observed on Sonneberg Observatory plates. Four additional possible outbursts, at plate limit, were also seen. The true position of V725 Aql is some 10-15 arcsec south of that shown in recently published finding charts.
