Quality flag (Q): I
Comments:
Identified as a synchrotron radio emitter by Benaglia et al (2020) on the basis of measurements at 325 and 610 MHz (negative spectral index). A visual companion has been identified by Mason et al. (2009) at 0.7'', but it may be too far to generate a sufficient wind interaction region. Another unseen companion may be present.
