MONSTER WAVES ON THE SUN: Data from NASA's STEREO spacecraft have confirmed the stunning reality of monster waves on the sun known as "solar tsunamis." Science@NASA has the full story.

DOUBLE FLYBY ALERT: Space shuttle Atlantis undocked from the International Space Station this morning at 4:53 am EST. The separation sets the stage for double flybys of North America on Wednesday evening, when Atlantis and the ISS will soar through the night sky side by side--a fantastic sight! Check the Simple Satellite Tracker for flybys.

Earlier this evening, astrophotographer Olivier Staiger caught the pair flying over the Swiss Alps:

"It was a little more than 7 hours after undocking," says Saiger. "A very nice flyby!"

NORTHERN LIGHTS: A solar wind stream is buffeting Earth's magnetic field and causing geomagnetic storms around the Arctic Circle. Last night in Lofoten, Norway, geoscientist Rob Stammes says the needle on his magnetograph spent the whole evening swinging wildly and he could see auroras beaming through the clouds. Not far away in Kvaløya, the sky was filled with green:

"The Northern Lights were everywhere--north, south, east and west," says photographer Fredrik Broms. "It was a magical sight."

Polar sky watchers should remain alert for auroras tonight as the solar wind continues to blow.

Near-Earth Asteroids
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 is on a collision course with our planet, although astronomers are finding new ones all the time.
On November 25, 2009 there were 1083 potentially hazardous asteroids.

Notes: LD means "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.
