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...

NASA Sun Observer Captures Two Solar Eruptions Over Four Hours
2012-11-17 15:28:22

[ Watch the Video: Double Prominence Eruptions ] Lawrence LeBlond for redOrbit.com - Your Universe Online On November 13, the Sun emitted an M6 classification solar flare, one of the weakest designations still able to cause some disturbances on Earth. Now, just a few days later, the Sun is at it again. NASA´s Solar Dynamic Observatory (SDO) caught spectacular images and video of the Sun bursting with two prominence eruptions over a four-hour period on November 16, between the...

Solar Plasma Wave Unleashed
2012-10-21 08:45:32

April Flowers for redOrbit.com - Your Universe Online NASA´s Solar Dynamics Observatory captured a spectacular solar eruption on Friday. A giant super-hot wave of solar plasma larger than the planet Earth erupted from the Sun at 4:15 a.m. EDT and was caught in amazing high-definition detail by the NASA spacecraft. "Once it started breaking away, the process only took 10 hours before it was out of sight," NASA media specialist Steele Hill explained in a photo description. "The...
