Draconids


In 1998, the great Draconid outburst was observed in Asia including Japan with ZHR 800. In 1933 and 1946, Draconid also presented outbursts around HR 10,000. The parant comet is 21P/Giacobini-Zinner(P=6.6years). The good condition for outburst is every 13 years (every 2-rev.) because of the relationship between the Earth and the parant comet orbit. The next is expected around 2011 - 2012.
Draconids is also called "Giacobinids" from the name of parant comet. The official list by The International Meteor Organization calls "Draconids" officially.
This meteor shower has the charactristic which is very slow speed of the geocentric velocity as 20km/s.
In Radio Meteor Observation, the outburst in 1998 was observed as same as visual observation. After that, however, it did not detect Draconid activity.
