Because of the large number of uncataloged asteroids near the PTF limit, our software requires at least two detections at a given location to flag a source as a bona fide transient e. In this work, we report the discovery by the Palomar Transient Factory PTF of PTF11agg, a rapidly fading optical transient associated with a year-long, scintillating radio counterpart. This scenario is also referred to as an interstellar medium ISM; Sari et al. In addition to cases where the observer is oriented directly along the jet axis i. We can use our NIR limits on the quiescent emission at the location of PTF11agg to calculate the minimum distance to an ultracool star as a function of spectral type; in other words, for each spectral type, any object closer than this "detectability" distance would be identified in our NIR imaging. To convert these to constraints on the outflow velocity, we use the redshift limits derived above: 0. But dwarf novae rarely exhibit coincident radio emission Benz et al. Finally, we can derive a lower limit on the distance to PTF11agg based only on the observed radio evolution. Finally, we briefly compare the observed properties with those of known extragalactic sources capable of generating relativistic ejecta in Section 4.
