Abstract: 
In 2003, with the use of Cherenkov telescope GT-48, it was detected an excess flux of very-high-energy gamma-quanta in a direction to the blazar 1ES 1959+650 at a level of about 30 % of the flux from Crab Nebula IE > 1 TeV) at 4.4 σ. Our analysis of observrd data showed the correlation of the emission intensity at E > 1 TeV with the emission in the energy band from 2 to 10 keV accordingly to ASM/RXTE data.
