Preliminary Analysis of Photometric Variations of the Central Star of the Planetary Nebula Sh 2–71

We confirm the presence of regular UBV (RI)C light variations of the object in the center of the planetary nebula Sh 2–71, with an improved period of P = 68.132 ± 0.005 days. The shapes and amplitudes of light curves, in particular colours, are briefly discussed.
