^^LEONID METEORS: Every year around this time, Earth glides through a minefield of debris from Comet 55P/Tempel-Tuttle. On Sunday, Nov. 19th, Earth will graze a cloud of comet dust, producing an outburst of Leonid meteors.
If forecasters are correct, the outburst will peak around 0445 UT on Nov. 19th (11:45 p.m. EST on Nov. 18th). The timing favors observers in Europe, Brazil and the Atlantic coast of North America, who could see as many as 100 meteors per hour |
