Subscribe to Space Weather News! MORE METEORS: Observers in China and Australia are reporting high meteor rates at 1830 UT, perhaps numbering one thousand or more per hour. This latest outburst is a result of Earth's passage through a dust cloud shed by Comet Tempel-Tuttle in 1866. Stay tuned for updates.  METEOR BLAST: It was a night to remember in the United States and Canada: A stunning display of Leonid meteors erupted after midnight on Sunday when Earth entered a dust cloud shed by Comet Tempel-Tuttle in 1766. Sky watchers in some places saw thousands of bright meteors per hour! Earth has since exited that cloud and plunged into another that has triggered an ongoing meteor storm over Australia and east Asian countries. More information:
GLOBAL LEONIDS: A NASA-led team of scientists is spread out around the globe to monitor Leonid meteor activity. Their preliminary report from the field: 1250 Leonid meteors per hour

Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs are on a collision course with our planet, although astronomers are finding new ones all the time.
On 18 Nov 2001 there were 344 known Potentially
Hazardous Asteroids Nov. - Dec. 2001 Earth-asteroid encountersNotes: LD is a "Lunar Distance." 1 LD = 384,401 km, the distance between Earth and the Moon. 1 LD also equals 0.00256 AU. MAG is the visual magnitude of the asteroid on the date of closest approach.
