October Draconids Meteor Shower (Peak Time and Condition)

October Draconids sometime shows strong activity. Recent outburst occured in 2018, 2012 and 2011. This meteor shower has the charactristic which is very slow geocentric velocity as 20km/s. Radio Meteor Observations is also possible to catch its activity when outburst occured. On the other hand, however, it is difficult to find a clear activity under not-outburst.
