The κ Cygnid (KCG) meteor shower exhibited unusually high activity in 2014, producing ten times the flux of KCG meteors compared to normal years. The shower was detected during the routine operation of several radar and optical systems. Meteoroids associated with the outburst ranged from approximately 10−6–10−5 kg for radar meteors and from 10−3 to 2 kg for optical meteors. The Canadian Meteor Orbit Radar, Czech part of the European Fireball Network, and NASA All Sky and Southern Ontario Meteor Networks produced thousands of KCG meteor trajectories in total. Using these data, we have undertaken a new and improved characterization of the dynamics of this little-studied, variable meteor shower. The KCGs have a diffuse radiant and a significant spread in orbital characteristics. Our analysis of the highest quality KCG trajectories reveals concentrations of stream members near major resonances with Jupiter. We conducted a new search for parent bodies and find that several known asteroids are orbitally similar to the KCGs. Our meteor stream simulations show that the two best parent body candidates readily transfer meteoroids to the Earth in recent centuries, but neither produces a match to the KCG radiant, velocity, and solar longitude. We nevertheless identify asteroid 2001 MG1 as a promising parent body candidate.
