Earth is approaching the orbit of Comet 55P/Tempel-Tuttle, source of the annual Leonid meteor shower. This is not a good year for Leonids. The shower's nominal peak on Nov. 17th is expected to produce no more than 15 meteors per hour. But! There is a chance of a surprise. Some forecasters believe that Earth might graze a 300-year-old stream of debris on Nov. 19th, producing an outburst of 50 to 200 meteors per hour. Its timing favors observers in the eastern half of North America, who should be alert for meteor activity this Saturday morning between 1:00 and 1:30 am EST. https://spaceweather.com/ Thanks for watching!
