A rapidly-developing sunspot
northeast of active region 9212 and another sizable spot rotating
into view over the Sun's eastern limb will increase the sunspot
number in the days to come. At present, none of the spots in
this SOHO white light image have magnetic fields more complex
than a beta configuration.
Coronal
Holes:
A coronal hole is developing
near the center of the solar disk. Our planet could pass through
a solar wind stream from the hole in 2 to 4 days. Image credit:

SOLAR WIND
SHOCK WAVE:
NASA's ACE spacecraft recorded an interplanetary shock wave at
1630 UT (11:30 am EST) on Oct. 31st when the solar wind velocity
soared from 360 km/s to nearly 500 km/s in less than 5 minutes.
Unfortunately for Halloween sky watchers, the shock wave did
not trigger widespread aurora.
The Oct. 31st
solar wind disturbance left the Sun on Oct. 29th when an M4-class explosion in the vicinity
of sunspot group 9209 launched a coronal mass ejection toward
Earth.
TRICK OR TREAT:
IT'S TOUTATIS! NASA
scientists are monitoring a large near-Earth asteroid that tumbled
past our planet on Halloween 2000. [FULL
STORY]
 WEEKEND AURORA: A coronal mass ejection struck Earth's
magnetosphere on Saturday, Oct. 28th, triggering aurora at high
latitudes over North America. For details and images, please
visit the Aurora
Gallery.
METEOR OUTLOOK: The Moon is only a few
days past New, affording dark skies for great meteor watching.
Upcoming highlights include the early-November Taurids. [details] Updated Oct. 27, 2000

The
Moonlit Leonids 2000 -- Our planet is heading
for a minefield of cosmic dust streams laid down by periodic
comet Tempel-Tuttle. The result could be a series of meteor outbursts
on Nov. 17 and 18, 2000.

filament collapsed and fell to the surface of the Sun, spawning
a coronal mass ejection that forecasters didn't expect.

Sunbathing
at Solar Max -- NASA scientists say that
solar maximum is now in full swing. Does that mean you're more
likely to suffer a sunburn at the beach? This story reveals the
answer.

A
Close Encounter with a Space Rock
-- A half-kilometer
wide asteroid zooms past Earth barely 12 times farther from our
planet than the Moon.

Extraordinary Geomagnetic Perseid Meteor Shower -- A
coronal mass ejection hit Earth's magnetosphere just before the
peak of the 2000 Perseid meteor shower.
Aug. 8, 2000: Perseid
Dawn -- Stargazers
could spot as many as 100 Perseid meteors per hour before dawn
on August 12.
