AURORA OUTLOOK: Earth is inside a gusty solar wind stream flowing from a coronal hole on the sun. Such streams often trigger auroras, but maybe not this time. The interplanetary magnetic field near Earth is tilting north--a condition which discourages geomagnetic storms.

CLOSE ENCOUNTER: The Moon and Mars were pleasingly close together this morning. North Americans up before dawn saw the pair less than one Moon-width apart, while Asian sky watchers had an even better view: the two were so close they almost "touched." California photographer Oded Regev took this picture from the campus of UC Berkeley. "It shows the Campanile tower with the Moon to its left and Mars to its right," he says.

The Moon and Mars are drifting apart now, but they will still be pleasingly close tonight. Take a look!



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 9 Sep 2003 there were 528 known Potentially
Hazardous Asteroids

Notes: 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.
