Space Weather News for Nov. 2, 2000
http://www.spaceweather.com
While asteroid Toutatis garnered plenty of attention as it passed by Earth
on Halloween, a newly-discovered space rock named 2000 UK11 glided by
almost 10 times closer than Toutatis during the early morning hours of
Nov. 1st.
Asteroid 2000 UK11, which was briefly visible through amateur telescopes,
is rapidly fading. But if you missed it, don't worry. There's
an even
brighter near-Earth object (NEO) on the way: 2000 UG11. Like
Toutatis and
2000 UK11, there is no danger of a collision with 2000 UG11, which will
pass 6 times farther from Earth than the Moon. Amateur astronomers
with 8
inch or larger telescopes and CCD cameras can spot the fast-moving NEO
early next week as it grows brighter than 14th magnitude.
In other news for sky watchers, SOHO coronagraphs recorded a solar coronal
mass ejection yesterday that could strike Earth's magnetosphere and
trigger geomagnetic activity this weekend.

There is a slight chance for middle-latitude aurora on Halloween night,
the result of a solar eruption on Sunday that probably sent a coronal mass
ejection in the direction of our planet. For details please visit

This morning a full halo coronal mass ejection sped away from the Sun
faster than 620 km/s. The leading edge of a solar wind shock wave
could
arrive in the neighborhood of Earth later this week and possibly trigger
auroras. For details and animations please visit

Space Weather News for Oct 12, 2000

NASA's ACE spacecraft recorded an interplanetary shock wave heading toward
Earth on October 12th at 2145 UT (5:45 pm EDT). Sky watchers should
be on
the alert for aurora between the times of local sunset on Oct. 12th and
sunrise on Oct 13th. The bright full Moon will likely outshine faint
aurora, but intense geomagnetic storms can produce auroras that are
visible in spite of lunar interference. For more information, please

Space Weather News for Sept 12, 2000

On Tuesday, Sept. 12, less than 24 hours after the sunspot number plunged
to its lowest value of the year, the Sun unleashed a surprising full-halo
coronal mass ejection (CME). The leading edge of the CME could reach
Earth on Thursday, Sept 14. Forecasters estimate a 30% chance of severe
geomagnetic disturbances (possibly including aurora) at middle latitudes
when the shock front arrives.

Telescopes monitoring the Sun recorded something extraordinary yesterday
-- the solar disk was nearly devoid of spots. With solar maximum in
full
swing, the Boulder sunspot number dropped to its lowest value of the year.
In spite of the "blank Sun," our planet could be in for a bit of
space
weather on Tuesday if, as expected, a solar coronal mass ejection that
left the Sun on Saturday strikes a glancing blow to Earth's magnetosphere.
The impact could trigger modest geomagnetic activity.
In other space weather news, astronomers have discovered a bright Near
Earth Asteroid that will pass by our planet on Sept. 17. Amateur
astronomers can monitor the fast-moving space rock in 8-inch or larger
telescopes.

Last night, during the peak of the Perseid meteor shower, a shock wave
from the Sun set off a beautiful display of aurora borealis.
Observers in
dark-sky areas across Canada and much of the United States were treated to
the unusual spectacle of meteors seen against a backdrop of colorful
Northern Lights. Auroras were spotted as far south as Los Angeles,
CA.
Conditions remain favorable for more aurora borealis Saturday night and
Sunday morning. Plus, the Perseid meteor shower is not entirely over.
Stargazers could see as many as 25 meteors per hour before dawn on Sunday,
Aug. 13.
If you have pictures of weekend auroras and/or Perseid meteors, we invite
you to submit them to SpaceWeather.com as an email attachment sent to
phillips@spacescience.com (Tony
Phillips).

coronal mass ejection that energized the ongoing geomagnetic storm, please
