During periods of strong geomagnetic storm activity, the Northern
Lights - aka Aurora Borealis - can sometimes be seen as far south
as California, Arizona or the Alps in Europe.

CALIFORNIA
AURORA - July 27, 2004
High, middle and low latitude regions
in North America witnessed strong auroral activity following the
arrival of a strong coronal mass ejection late on July 26 (associated
with a long-duration M1 solar flare on July 25). Low latitude
sky watchers in Utah, Nevada and California
witnessed auroral activity early on July 27. |

NORTHERN
LIGHTS IN CALIFORNIA - October 29, 2003
A historic geomagnetic storm: Two
powerful coronal mass ejections associated with X17.2 and X10.0
solar flares impacted the Earth on October 29 and 30, followed
by severe to extreme geomagnetic storm
conditions. Spectacular
auroral displays have been observed as far south as
California,
Arizona, Texas and Florida.

PERSEID
METEOR SHOWER - August 11-12, 2002
The Perseids are fast and colorful shooting stars
- often rich in bright meteors with long-lasting trains. 60 to
80 meteors per hour are usually seen during the peak of the shower.

THE
PLANETARY ALIGNMENT OF SPRING 2002
Bright Jupiter, yellow
Saturn, rusty-red Mars, blazing Venus and glimmering Mercury gathered
for a brilliant show across the western evening sky. A fine crescent
moon added to an already dazzling visual feast between May 13
- 16. The finest planetary conjunction for decades to come...

THE
2001 LEONID METEOR STORM - November 18, 2001
The display began on Sunday morning when
Earth entered a dust cloud shed by Comet Tempel-Tuttle in 1766.
The Leonids of 2001 may be regarded as the largest meteor shower
of our lifetime - more than 1000 meteors per hour rained over
North America and Hawaii.
Location: Mojave Desert, California

NORTHERN
LIGHTS IN CALIFORNIA - November 5, 2001
A powerful coronal
mass ejection billowed away from the Sun on November 4 and swept
past our planet on the following day. The impact was followed
by severe geomagnetic storm conditions and visible auroral activity
as far south as Florida, Texas and California
in the United States. Northern Lights are rarely seen at low latitudes,
occurring only 3 - 6 times during the 11-year solar cycle. |
