Rare outbursts in activity can occur when the Earth travels through a denser part of the cometary debris stream; for example, in 1998, rates suddenly spiked but only increased modestly in 2005. A Draconid meteor outburst occurred as expected on October 8, 2011, though a waxing gibbous Moon reduced the number of meteors observed visually. During the 2012 shower, radar observations (which detect smaller and fainter meteors...
