Abstract: We report a serendipitous hard X-ray (3-24 keV) detection of the blazar LBQS 1319+0039. The X-ray spectrum is consistent with powerlaw emission with a photon index of $\Gamma = 1.78$. The observed emission and published redshift imply an observed 2-10 keV luminosity of $3.4\times10^{45}$ erg s$^{-1}$. This is consistent with extrapolations from a previous soft X-ray detection, thus there is no evidence for strong variability.<br />Comment: published in Research Notes of the American Astronomical Society
