The data of BVR observations of the middle-age radio pulsar PSR 0656+14 on January , 20/21 at the BTA ( 6-m ) are presented .
The brightness is determined in Cousins B filter B \approx 25.1 with \lambda _ { eff } = 4448 \AA in adjacent for HST F130LP long-pass filter of a star-like object , coinciding with the position of VLA radio source .
Relatively large observed V and R fluxes ( ^ { < } _ { \sim } 3 \sigma or > 10 ^ { -30 } ergs cm ^ { -2 } s ^ { -2 } Hz ^ { -1 } ) can witness a non-thermal nature of optical radiation of this pulsar up to \lambda \approx 6600 \AA .
Most probably , in the UV-optical ( BVR ) spectral range a power-law spectrum is superimposed on the thermal-like radiation of the entire neutron star surface what can be related to a mechanism itself of the pulsar activity .
