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 obser ved during a campaign on dMe stars in April 1996. Cross correlating the coo rdinates, we found an entry in the NRAO NVSS survey catalog at 1.4 GHz. Acc ording to the rules of this survey, we named this serendipitous source "NVS S J191656+051126". No optical or X-ray counterpart could be identified, whi le we fmd that the IRAS point source IRAS 19145+0505 could be the IR counte rpart. Using the radio data, we determined that the source spectral index i s compatible with synchrotron emission mechanism. We have also investigated the structure of the source that is resolved into two components and their time variability.
