Near Miss: The Solar Superstorm Of July 2012

Dr. Tony Phillips, Science@NASA If an asteroid big enough to knock modern civilization back to the 18th century appeared out of deep space and buzzed the Earth-Moon system, the near-miss would be instant worldwide headline news. Two years...

Karen C. Fox, NASA's Goddard Space Flight Center The sun emitted a mid-level solar flare, peaking at 12:20 p.m. EDT on July 8, 2014, and NASA's Solar Dynamics Observatory captured images 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 see...

IRIS Solar Observatory After 1 Year In Space
2014-06-27 03:09:48

[ Watch The Video: A First For IRIS: Observing A Gigantic Solar Eruption ] Karen C. Fox, NASA On June 27, 2013, NASA's newest solar observatory was launched into orbit around Earth. The Interface Region Imaging Spectrograph, or IRIS, observes the low level of the sun's atmosphere -- a constantly moving area called the interface region -- in better detail than has ever been done before. During its first year in space, IRIS provided detailed images of this area, finding even more...

3 x-class flares
2014-06-11 08:40:19

UPDATE - June 11, 2014 On June 11, 2014, the sun erupted with its third X-class flare in two days. The flare was classified as an X1.0 and it peaked at 5:06 a.m. EDT.  Images of the flare were captured by NASA's Solar Dynamics Observatory. All three flares originated from an active region on the sun that recently rotated into view over the left limb of the sun. ----- UPDATE - June 10: The sun released a second X-class flare, peaking at 8:52 a.m. EDT on June 10, 2014.  This is...

New Jersey Institute of Technology The 1.6 meter telescope at Big Bear Solar Observatory (BBSO) in California has given researchers unparalleled capability for investigating phenomena such as solar flares. Operated by New Jersey Institute of Technology (NJIT), the BBSO instrument is the most powerful ground-based telescope dedicated to studying the star closest to Earth. On June 2, Distinguished Professor of Physics Haimin Wang joined NJIT colleagues at the 224th meeting of the...

Karen C. Fox, NASA's Goddard Space Flight Center [ Watch the Video: A First For IRIS: Observing A Gigantic Solar Eruption ] A coronal mass ejection, or CME, surged off the side of the sun on May 9, 2014, and NASA's newest solar observatory caught it in extraordinary detail. This was the first CME observed by the Interface Region Imaging Spectrograph, or IRIS, which launched in June 2013 to peer into the lowest levels of the sun's atmosphere with better resolution than ever before. Watch...

Lauren Gaches/Rob Gutro - NOAA/NASA Goddard Space Flight Center Two of the six instruments that will fly on NOAA's first Geostationary Operational Environmental Satellite - R (GOES-R) satellite have completed integration with the spacecraft. The Solar Ultraviolet Imager (SUVI) and Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS) were installed on the sun-pointing platform. They will observe the sun and space weather, including coronal mass ejections, solar flares and ion fluxes that...

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...

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...
