Orionids


Since Orionids is the second firstest meteor shower, a lot of bright meteors and trains are observed. The parant comet is 1P/Halley. In 2006 and 2007, outburst activities were observed in the world.
In Radio Meteor Observation, it is not too much meteor echoes because the geocentric velocity is very fast as 66km/s. In 2006 and 2007, however, outbusts were observed as same as visual observation.
Although a lot of meteor echoes are not observed, a lot of long echoes are observed.
