KAMIKAZE COMET: Yesterday coronagraphs on board the Solar and Heliospheric Observatory recorded a bright comet (pictured right) disintegrating as it plunged toward the Sun. Amateur astronomer Sebastian Hönig spotted the "sungrazer" in online images at the SOHO web site, marking the 347th time someone has found a new comet by watching SOHO coronagraphs. SOHO-347, like most known sungrazing comets, is likely to be a fragment from a single giant comet that broke apart long ago.

SOLAR WIND: Earth is slowly exiting a high-speed solar wind stream that continues to buffet our planet's magnetosphere. Geomagnetic conditions have been unsettled since Sept. 3rd, but not stormy. Nevertheless, high-latitude sky watchers should remain alert for auroras.

SUNSPOT WATCH: A new and potentially menacing sunspot group, numbered 9608, is emerging near the Sun's southeastern limb. Extreme ultraviolet images of the active region, like the one pictured right from SOHO, reveal tangled loops of hot gas arcing high above the sunspot group -- a telltale signature of complex magnetic fields that harbor energy for powerful explosions.

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 6 Sep 2001 there were 318 known Potentially
Hazardous Asteroids
