We report the discovery of a new eclipsing system less than one arcminute south of the pulsating DB white dwarf KUV 05134+2605 .
The object could be identified with the point source 2MASS J0516288+260738 
published by the Two Micron All Sky Survey .
We present and discuss the first light curves as well as some additional colour and spectral information .
The eclipse period of the system is 1.29 d , and , assuming this to be identical to the orbital period , the best light curve solution yields a mass ratio of m _ { 2 } /m _ { 1 } = 0.11 , a radius ratio of r _ { 2 } /r _ { 1 } \approx 1 and an inclination of 74 ^ { \circ } .
The spectral anaylsis results in a T _ { eff } = 4 200 K for the primary .
On this basis , we suggest that the new system probably consists of a late K + Brown dwarf ( which would imply a system considerably younger than \approx 0.01 Gyr to have r _ { 2 } /r _ { 1 } \approx 1 ) , and outline possible future observations .
