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 ispresented. The PDM method for period analysis (Stellingwerf 1978) is used. Thephotometric data is modulated with a period of 0.156 +- 0.001 d. Following thesinusoidal shape of the phased light curve, we interpret this periodicity aspossibly orbital in nature which is consistent with a cataclysmic variableabove the period gap.Comment: 4 pages, 4 figures, accepted for publication in A&
