    old crap from 2010
    In April 2010, radio astronomers working at the Jodrell Bank Observatory of the University of Manchester in the UK reported an object in M82 that had started sending out radio waves, and whose emission did not look like anything seen anywhere in the universe before.[19]

    There have been several theories about the nature of this object, but currently no theory entirely fits the observed data.[19] It has been suggested that the object could be an unusual “micro quasar”, having very high radio luminosity yet low X-ray luminosity, and being fairly stable, it could be an analogue of the low X-ray luminosity galactic microquasar SS 433.[20] However, all known microquasars produce large quantities of X-rays, whereas the object’s X-ray flux is below the measurement threshold.[19] The object is located at several arcseconds from the center of M82 which makes it unlikely to be associated with a supermassive black hole. It has an apparent superluminal motion of four times the speed of light relative to the galaxy center.[21][22] Apparent superluminal motion is consistent with relativistic jets in massive black holes and does not indicate that the source itself is moving above lightspeed.[21]
