Solar Flares

January 9, 2010 | By Mark K. Matthews
NASA heads into 2010 with the bittersweet assignment of retiring the space shuttle after nearly three decades. But the agency also plans to launch three new satellites aimed at better understanding the sun and Earth's climate and oceans. Two satellites will examine Earth -- specifically, the concentration of salt in the world's oceans and the presence of aerosols, or minute particles, such as dust or ash, in the atmosphere. A third satellite mission will study the sun and its effect on space weather, including solar flares that can disrupt communication on Earth.

"Space: Magic Tree House Research Guide" Will Osborne and Mary Pope Osborne When you read this book you can find out a million new things about space. Did you know that the sun can burst solar flares? If you like space, read this book. You will find out things you never knew!

It is funny because it is about a chick who wants to become a duck.

Twin spacecraft blasted off on a mission to study huge eruptions from the sun that can damage satellites, disrupt electrical and communications systems on Earth, and endanger spacewalking astronauts. The two NASA spacecraft, known as STEREO, for Solar Terrestrial Relations Observatory, lifted off Wednesday from Cape Canaveral in Florida, aboard a Delta II rocket.

Even astronomers can take the sun -- glowing steadily for more than 4 billion years and rising unfailingly every morning -- for granted. Among the 100 billion stars in the Milky Way, ours is rather lackluster. But the sun certainly is demanding everyone's attention now, three weeks into perhaps the most dramatic and unexpected chain of eruptions ever observed venting from its seething, bubbling surface. There have been as many as 11 salvos since Oct. 19.

A solar flare that burst out of the sun Tuesday was the largest on record. The two previous most powerful flares, from 1989 and 2001, were rated at X-20 on the scale used by solar astronomers. Tuesday's event was at least an X-28 and could be revised upward. The flare was so powerful it "blinded" the satellite used to measure it for 11 minutes. The flare caused few problems on Earth because it was directed away from the planet and hit only with a glancing blow.

One of the most powerful solar flares in nearly 30 years erupted from the sun's surface early Tuesday morning, ejecting a titanic blast of gas, radiation and matter toward Earth. Space weather forecasters said the event could lead to a geomagnetic storm today and Thursday that could disrupt power lines and impair satellite and radio communications, although the power of the storm remained uncertain.

Forecasters said a solar flare was the most intense they have seen in the current 11-year solar cycle. Space weather forecasters in Boulder estimated its intensity at X-22 on a scale that goes only to 20 after sensors on a National Oceanic and Atmospheric Administration satellite could no longer measure it. Forecasters said the estimate could be off by plus or minus 2. The flare caused static on a radio frequency used to navigate boats and planes, causing flight delays.

Four solar flares and a pair of powerful magnetic gas clouds spawned in a monster sunspot were headed for Earth and could affect power systems, satellites and some radio transmissions this weekend, a top space weather forecaster said. They might also provide a dazzling display of the northern lights if they arrive at night, said Gary Heckman, senior forecaster for the U.S. Space Environment Center in Boulder, Colo.

A NASA spacecraft on a seven-year mission to collect comet dust survived a zap from an enormous solar flare this month. The Stardust spacecraft was hit Nov. 9 by a storm of high-energy particles 100,000 times more intense than usual, according to the Jet Propulsion Laboratory in Pasadena, which manages the mission. The spacecraft was 130 million miles away from the sun when it was struck, the National Aeronautics and Space Administration said.

A severe geomagnetic storm that hit Earth this weekend interfered with data from at least one U.S. weather satellite and some power systems, government scientists said. But space weather forecasters at the National Oceanic and Atmospheric Administration (NOAA) Space Environment Center in Boulder, Colo., said the worst of Saturday's storm, caused by a huge solar flare on Friday, was over.
