DRACONID METEOR OUTBURST IS SUBSIDING:

SPACEWEATHER

 An outburst of more than 1000 meteors per hour on Oct. 8th is subsiding now. The Canadian Meteor Orbit Radar (CMOR) detected the surge in activity around 16:00 UT as Earth was passing through a network of debris streams from comet 21P/Giacobini-Zinner, source of the annual Draconid meteor shower. The outburst appears to have been caused by a filament of comet dust shed by Giacobini-Zinner in the year 1959. "This event follows in the grand tradition of short, intense Draconid outbursts," says Bill Cooke of NASA's Meteoroid Environment Office. Visual reports of the outburst are sparse, which suggests it was faint--i.e, better seen by a radar than by the human eye. Stay tuned for updates.
