摘要：

Aims. Period analysis of CCD photometry of V1493 Aql (Nova Aql 1999 No. 1) performed during 12 nights through I and R filters a few weeks after maximum is presented. Methods. The PDM method for period analysis (Stellingwerf 1978, ApJ, 224, 953) is used. Results. The photometric data is modulated with a period of 0.156 +/- 0.001 d. Following the sinusoidal shape of the phased light curve, we interpret this periodicity as possibly orbital in nature and that is consistent with a cataclysmic variable above the period gap.
