Abstract

We present new Very Large Array (VLA) radio observations in X, U, K, and Q bands (from 8.4 to 43 GHz) of a serendipitously detected radio source observed during a campaign on dMe stars in April 1996. Cross correlating the coordinates, we found an entry in the NRAO NVSS survey catalog at 1.4 GHz. According to the rules of this survey, we named this serendipitous source "NVSS J191656+051126". No optical or X-ray counterpart could be identified, while we find that the IRAS point source IRAS 19145+0505 could be the IR counterpart. Using the radio data, we determined that the source spectral index is compatible with synchrotron emission mechanism. We have also investigated the structure of the source that is resolved into two components and their time variability.
