Friday night, the light from solar flares was reported
near cities including Palm
Springs and Sacramento, California; Flagstaff,
Arizona; and Albuquerque and
Carlsbad, New Mexico.
Solar storms could affect telecommunications

BOULDER, Colorado (AP) -- Intense
storms raging on the sun made Friday
night's sky shimmer red and green as far
south as Palm Springs, California, and
southern New Mexico, and scientists say
the storms could briefly disrupt
telecommunications as they continue
through the weekend.
The biggest sunspot cluster seen in at
least 10 years has developed on the upper
right quarter of the side of the sun visible
from Earth, according to satellite readings.
Friday night, the light from solar flares was reported
near cities including Palm
Springs and Sacramento, California; Flagstaff,
Arizona; and Albuquerque and
Carlsbad, New Mexico.
"It has totally lit up the sky. We've had dozens and
dozens of calls. People want to know what it is,"
said Bill Seigel, a producer at radio station KESQ in
Palm Desert, 115 miles east of Los Angeles. "Some
people thought it was UFOs."
Just north of Albuquerque, David MacKel was
making the rounds at his security job when he saw
the lights. He noted it on his report at 11:23 p.m.
"It was blood red. That's all I can say. It was kind
of opaque and you could see the stars through it,"
MacKel said. He said he had seen the Northern
Lights while in Alaska, but "the Northern Light
move, this was more gaseous. It kind of got me
freaked out."
Deputy Danny Gonzales of Eddy County, New
Mexico, described it as a purple haze. "It was very
distinct in color," he said. "I have never seen
anything like it."
Anthony Watts, a
meteorologist in Chico,
California, about 170
miles north of San
Francisco, said the glow
from the coronal
mass ejection was
interesting, but posed
no threat.
"There's no danger,
however there is the
likelihood that we'll
have radio or
television
interruptions," Watts said.
The sunspot, which is a
cooler, darker
region on the sun's
surface, is caused by
a concentration of
temporarily distorted
magnetic fields. It
spawns tremendous
eruptions, or flares,
into the sun's
atmosphere, hurling
clouds of electrified
gas toward Earth.
The solar activity can
produce an aurora
in the night sky,
typically over northern
latitudes. The colorful,
shimmering glow
occurs when the energetic
particles strike
the Earth's upper
atmosphere.
NASA scientists said a powerful flare that erupted
Thursday rated a class X, the
most potent category.
The eruptions triggered a powerful, but brief,
blackout Friday on some
high-frequency radio channels and low-frequency
navigational signals, scientists
said. They forecast at least a 30 percent chance of
continuing disruptions through
Sunday.
