Subscribe to Space Weather News! SOLAR ACTIVITY: Sunspot 9704 has developed a twisted delta-class magnetic field. As a result, the large spot poses a threat for strong Earth-directed explosions as it crosses the face of the Sun during the days ahead.  METEOR STORM: Sky watchers who saw it will never forget it: the 2001 Leonid meteor storm.
The display began on Sunday morning, Nov. 18th, when Earth glided into a dust cloud shed by comet Tempel-Tuttle in 1766. Thousands of meteors per hour rained over North America and Hawaii. Then, on Monday morning Nov. 19th (local time in Asia), it happened again: Earth entered a second cometary debris cloud from Tempel-Tuttle. Preliminary reports from China, Korea and Japan indicate 2,000 to 6,000 meteors per hour -- possibly more -- falling over east Asian countries and Australia. Stay tuned for updates.

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 19 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.
