We present an analysis of light variations in UBV ( RI ) _ { C } of the anomalous object in the center of planetary nebula Sh 2-71 .
We refined the linear ephemeris of the light maxima to \mathrm { JD _ { max } } = 2449862.0 + 68.101 ~ { } ( E - 96 ) , but also identified long-term , obviously non-periodic variations .
The latter manifest themselves in large O-C shifts , a variable profile of light curves ( hereafter LC ) and changes in the mean brightness of the object .
Our spectroscopic observations suggested the presence of a superdense nebula in the center of Sh 2-71 .
