Serendipitous Hard X-ray Detection of a Blazar

5 October 2018

During NuSTAR observations we obtained a serendipitous detection of the blazar LBQS 1319+0039. The blazar was found to have a luminosity consistent with extrapolations from previous soft X-ray observations and thus does not appear to be systematically varying. We have published our detection in the Research Notes of the American Astronomical Society.
