Aslan, Turkish National Observatory, Turkish National Research Council (TUBITAK), report that R-band CCD photometry, obtained with the new Russian-Turkish 1.5-m telescope at TUBITAK National Observatory, Antalya, during 2002 June 10, 12, Oct. 1, 2, 3, 5, Dec. 1, and 22 reveals the presence of large variations in the light curve of this classical nova (IAUC 7686), with a period of either 0.463 ± 0.014 day or the 1-day alias at 0.316 ± 0.007 day. The semi-amplitude of the variations is about 0.5 mag. If the 0.463-day modulation is the correct period, the system has wide eclipses. Further observations are encouraged.
