M-class Solar Flare
2014-04-03 06:12:35

Karen C. Fox, NASA's Goddard Space Flight Center On April 2, 2014, the sun emitted a mid-level solar flare, peaking at 10:05 a.m. EDT, and NASA's Solar Dynamics Observatory captured imagery of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. To...

University of Cambridge Video of magnetic field lines 'slipping reconnection' bring scientists a step closer to predicting when and where large flares will occur Scientists have for the first time witnessed the mechanism behind explosive energy releases in the Sun's atmosphere, confirming new theories about how solar flares are created. New footage put together by an international team led by University of Cambridge researchers shows how entangled magnetic field lines looping from...

Extreme Space Weather In 2012 Resulted In Fastest Solar Wind Speed Ever Recorded
2014-03-19 05:25:02

[ Watch the Video: STEREO Captures Fastest CME to Date ] redOrbit Staff & Wire Reports - Your Universe Online Researchers have uncovered the origin and cause of an extreme space weather event that took place July 22, 2012 on the sun which generated the fastest solar wind speed ever recorded directly by a solar wind instrument. The formation of the powerful event showed remarkable features as a massive cloud of solar material erupted off the sun's right side, zooming out into...

Mid-Level Solar Flare Seen By NASA's Solar Dynamics Observatory
2014-03-13 12:05:22

Karen C. Fox, NASA The sun emitted a mid-level solar flare, peaking at 6:34 p.m. EDT on March 12, 2014, and NASA's Solar Dynamics Observatory, or SDO, captured an image of it. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. To see how this event may...

Van Allen Probes Helping To Refine Space Weather Computer Models
2014-03-10 07:45:30

redOrbit Staff & Wire Reports - Your Universe Online Data from the Van Allen Probes has been combined with a high-powered computer model to help researchers test and improve the forecast model to determine how the two giant near-Earth radiation belts they orbit can affect technology in space, NASA officials reported on Friday. The Van Allen radiation belts, which are teeming with rapidly-moving particles and a space weather system that varies in response to incoming solar particles...

Space Weather Shielding Provided By Plasma Plumes
2014-03-07 05:41:48

April Flowers for redOrbit.com - Your Universe Online The magnetosphere, Earth's magnetic field, stretches from the core of the planet out into space. Here, the magnetosphere meets the solar wind, a stream of charged particles emitted by the sun. The magnetosphere, for the main part, acts to shield the Earth from this high-energy solar activity. When the Earth's magnetosphere comes into contact with the sun's magnetic field in a process called "magnetic reconnection," the Earth's...

sunspot
2014-03-01 05:57:56

Karen C. Fox, NASA's Goddard Space Flight Center A giant sunspot – a magnetically strong and complex region on the sun's surface – has just appeared over the sun's horizon. This is the third trip for this region across the face of the sun, which takes approximately 27 days to make a complete rotation. Scientists track sunspots that are part of active regions, which often produce large explosions on the sun such as solar flares and coronal mass ejections, or CMEs. Each time an active...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...

Solar Physics
2012-05-02 19:16:53

Solar Physics is a journal for solar and solar-stellar research and the study of solar terrestrial physics. Founded in 1967 by solar physicist Cornelis de Jager and publisher D. Reidel, the journal treats all aspects of solar physics, ranging from the internal structure of the Sun and its evolution, to outer corona and solar wind in interplanetary space. Solar Physics has four more than forty years been the principal journal for publications of fundamental research on the Sun. It is...

A Radio Atmospheric signal (sometimes referred to as Sferic or Spheric), is a broadband electromagnetic impulse that occurs during atmospheric lightning discharges. Sferics spread out from the lightning source and can be received thousands of miles away. A sferic, depending on atmospheric conditions, may extend anywhere from a few kHz to several tens of kHz. Sferics from far reaching storms, over 1500 miles away, are generally offset in frequency range and may be picked up as tweeks. A...

Hannes Olof Gösta Alfvén (May 30, 1908 - April 2, 1995) was a Swedish plasma physicist born in Norrköping, Sweden. Alfvén received his PhD from the University of Uppsala in 1934. His thesis was titled "Investigations of the Ultra-short Electromagnetic Waves." He was originally trained as an electrical power engineer and later moved on to research and teaching in the fields of plasma physics. Alfvén made many contributions to plasma physics, including theories describing the...

Ring Current
2004-10-19 04:45:44

Ring Current -- A ring current is an electric current carried by charged particles trapped in a planet's magnetosphere. It is caused by the longitudinal drift of energetic (10-200 keV) particles. Earth's Ring Current Earth's ring current is responsible for geomagnetic storms. The ring current system consists of a band, at a distance of 3-5 RE(1), which lies in the equatorial plane and circulates clockwise around the Earth (when viewed from the north). The particles of this region...
