Abstract  OO Aql was targeted for observation since its short orbital period (~0.5d) and eclipse duration (~3 hours) were amenable to investigation over a relatively short viewing campaign at a location with less than optimal viewing conditions. Analysis of clear filter CCD data collected over a ten-week period has led to a revised linear ephemeris equation (Min. I (hel.) = 2438613.1037 ± 0.0073 + 0.5067936 ± 0.0000003 E) for OO Aql.
