First
Images From Hinode Offer New Clues About Our Violent Sun
(NASA News) - December
22, 2006
WASHINGTON
- Instruments aboard a Japan Aerospace Exploration Agency satellite
named Hinode, or "Sunrise," are returning extraordinary
new images of our sun. The international mission to study the
forces that drive the violent, explosive power of the sun launched
from Japan in September.

Space Station Glitch Possibly Caused by Solar Flare
(SPACE.com) - December

HOUSTON --
A glitch in the International Space Station’s (ISS) U.S.-built
attitude control system may have its root in a massive solar
flare that erupted from the Sun this week, a NASA flight director
said Friday.

the Sun. What did it look like? A picture is worth a thousand

Mark your
calendar: On Wednesday, Nov 8th, the planet Mercury will pass
directly in front the Sun. The transit begins at 2:12 pm EST
(11:12 am PST) and lasts for almost five hours. Good views can
be had from the Americas, Hawaii, Australia and all along the
Pacific Rim: visibility map.
Surprises
from the Edge of the Solar System
(NASA Feature) - September
21, 2006
Almost every
day, the great antennas of NASA's Deep Space Network turn to
a blank patch of sky in the constellation Ophiuchus. Pointing
at nothing, or so it seems, they invariably pick up a signal,
faint but full of intelligence. The source is beyond Neptune,
beyond Pluto, on the verge of the stars themselves.

Sentinels (NASA Feature)

1, 2006
In his 1970s
book, Space, James Michener depicted a fictional Apollo
mission that lost its crew to radiation from a massive solar
flare. He based his tale on what easily might have been but
for lucky timing: a massive flare on Aug. 7, 1972 occurred between
Apollo 16 (April) and Apollo 17 (December), mankind's last journeys
to the Moon. The event still resonates today.
A
Summer Flare from the Sun to the Earth (NASA Feature)

Scientists
say that the next solar cycle of activity is close-by; read
Backward
Sunspot to check out the sunspot that may be starting the
whole process. In
the meantime, this large sunspot, named Active Region 904, has
been sputtering on for days on end. After watching it rotate
into view on Aug. 9, it finally popped off a modest (C-class)
flare and associated coronal mass ejection (CME) on Aug. 17
when it had rotated into a location where it practically faced
Earth.

Backward
Sunspot
(NASA Feature) - August 15, 2006
On July 31st,
a tiny sunspot was born. It popped up from the sun's interior,
floated around a bit, and vanished again in a few hours. On
the sun this sort of thing happens all the time and, ordinarily,
it wouldn't be worth mentioning. But this sunspot was special:
It was backward.

Ends Sun's Quiet Spell (NASA Featured Image)- July 7, 2006
After a long quiet spell without any strong solar
storms, the sun unleashed a flare (M-class, which means moderate)
and a fairly substantial coronal mass ejection on July 7.
NASA
and NSF Computers Simulate Sun's Corona (NASA Feature)-
June
26, 2006 For
the first time, researchers have developed a computer simulation
that can accurately create a model of the sun's outer atmosphere,

the computer model marks the beginning of a new era in space
weather prediction.

Long
Range Solar Forecast (NASA Feature)- May 10, 2006
The
Sun's "Great Conveyor Belt" has slowed to a record-low
crawl, which has important implications for future solar activity:
Solar Cycle 25 peaking in 2022 could be one of the weakest in
centuries.

Sees Eclipse in a Different Light
(NASA Feature)- March 27, 2006
It's
not easy to see a total solar eclipse. They're rare -- the next
one visible in the U.S. is in 2017 -- and you can't look directly
at them. But in the early morning hours of March 29, seeing the
next solar eclipse will be easy -- just visit this Web page.

It's
official: Solar minimum has arrived. Sunspots have all but vanished.
Solar flares are nonexistent. The sun is utterly quiet.
Like
the quiet before a storm.
Recently
researchers announced that a storm is coming--the most intense
solar maximum in fifty years.

Storms: Nowhere to Hide from SOHO's Improved 'X-Ray Vision'
(NASA Feature)- March 9, 2006
NASA
researchers using the Solar and Heliospheric Observatory (SOHO)
spacecraft have developed a method of seeing through the sun to
the star's far side. The sun's far side faces away from the Earth,
so it is not directly observable by traditional techniques.

Gaze Inside Sun, Predict Strength of the Next Solar Cycle (NASA
- Goddard Space Flight Center News)- March 6, 2006
The
next solar activity cycle will be 30 to 50 percent stronger than
the previous one, and up to a year late in arriving, according
to a breakthrough forecast by Dr. Mausumi Dikpati and colleagues
at the National Center for Atmospheric Research (NCAR) in Boulder,
Colo. The scientists made the first "solar climate" forecast using
a combination of groundbreaking observations of the solar interior
from space and computer simulation. NASA's Living With a Star
program and the National Science Foundation funded the research.
