NASA's SDO Spots A Summer Solar Flare

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...

solar mini-max
2014-06-11 11:02:39

Brett Smith for redOrbit.com - Your Universe Online Our Sun is constantly cycling between periods of low activity and high activity – known as solar minimum and solar maximum, or Solar Max, respectively. In 2008 and 2009, NASA’s solar experts reported they were surprised to see the Sun descend into one of its deepest solar minimums in recorded history. But now, NASA observers are saying that the solar minimum is almost over. [ Watch the Video: ScienceCasts: Solar Mini-Max ]...

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...

Mid-level Solar Flare 050814
2014-05-08 12:01:48

Karen C. Fox, NASA's Goddard Space Flight Center The sun emitted a mid-level solar flare, peaking at 6:07 a.m. EDT on May 8, 2014, and NASA's Solar Dynamics Observatory, or SDO, captured images 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...

IRIS Spotted Its Largest Solar Flare In January
2014-02-22 05:28:40

[ Watch the Video: IRIS Spots Its Largest Solar Flare ] April Flowers for redOrbit.com - Your Universe Online The strongest solar flare since NASA's Interface Region Imaging Spectrograph (IRIS) launched in the summer of 2013 was observed on January 28 of this year. Solar flares are bursts of X-rays and light that stream out into space, disrupting long-range radio transmission on Earth and satellite functions in space. What sets them off, however, is still a mystery for scientists....

First X-class Flare Of 2014 Unleashed By The Sun
2014-01-08 10:55:47

[ Watch The Video: SDO Captures Release of X1.2 Class Solar Flare ] NASA Update: January 8, 2014 The Jan. 7, 2014, X-class flare was also associated with a coronal mass ejection, or CME, another solar phenomenon that can send billions of tons of particles into space that can reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground. The European...

Sun Emits Mid Level Solar Flare Jan. 7, 2014
2014-01-07 12:11:43

NASA The sun emitted a mid-level solar flare, peaking at 5:13 a.m. EST on Jan. 7, 2014. Images of the flare were captured by NASA's Solar Dynamics Observatory and showed that it came from an active region on the sun that currently sports one of the largest sunspots seen in the last 10 years. Sunspots are regions of strong and complex magnetic fields on the sun's surface. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere...

Third Solar Flare Emitted By The Sun In Two Days
2013-10-25 12:12:19

NASA [ Watch The Video: Experimental NASA Research Model of Path for Oct. 22-23 CMEs ] The M9.4 flare on Oct. 23, 2013, was associated with a coronal mass ejection or CME, a solar phenomenon that can send billions of tons of particles into space that can reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground. Another solar flare erupted from the same area...

Sun Produces An X1.7 Solar Flare, Followed By An X2.8
2013-05-13 12:04:28

Lawrence LeBlond for redOrbit.com - Your Universe Online On Sunday (May 12) the Sun emitted a significant solar flare that is being classified as the first X-class event of 2013. The X1.7 flare, which peaked at about 10 p.m. EDT, was also associated with another solar event known as a coronal mass ejection (CME). While CMEs can release radiation and solar material in the direction they were produced, Sunday´s phenomenon was not directed at Earth. While solar flares also have the...

Three Coronal Mass Ejections And A Solar Flare In Three Days On The Sun
2013-04-22 11:25:57

Lawrence LeBlond for redOrbit.com - Your Universe Online NASA´s Solar Dynamics Observatory (SDO) recorded a coronal mass ejection (CME) on Saturday April 20, 2013, at 2:54 a.m. EDT. That was only to be the first of three such events over the course of the weekend. CME´s, solar phenomena that send billions of tons of solar particles and radiation speeding through space at over 500 miles per second, have the potential to affect communication systems and electronics here and in...

Fast-Growing Sunspot Observed By NASA's SDO
2013-02-20 14:28:12

NASA As magnetic fields on the sun rearrange and realign, dark spots known as sunspots can appear on its surface. Over the course of Feb. 19-20, 2013, scientists watched a giant sunspot form in under 48 hours. It has grown to over six Earth diameters across but its full extent is hard to judge since the spot lies on a sphere not a flat disk. The spot quickly evolved into what's called a delta region, in which the lighter areas around the sunspot, the penumbra, exhibit magnetic fields...


Word of the Day
callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
