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...

Mid-Level Flare Emitted By The Sun
2013-04-11 14:08:16

NASA The M6.5 flare on the morning of April 11, 2013, was also associated with an Earth-directed coronal mass ejection (CME), another solar phenomenon that can send billions of tons of solar particles into space and can reach Earth one to three days later. CMEs can affect electronic systems in satellites and on the ground. Experimental NASA research models show that the CME began at 3:36 a.m. EDT on April 11, leaving the sun at over 600 miles per second. Earth-directed CMEs can cause a...

Powerful Coronal Mass Ejection Erupts On Sun's Earth-Facing Side
2013-03-15 13:42:58

Lawrence LeBlond for redOrbit.com - Your Universe Online A powerful solar eruption occurred on the surface of the sun at 2:54 a.m. (EDT) this morning. The eruption, called a coronal mass ejection (CME), occurred on the Earth-facing side of the sun and may have released billions of tons of solar particles into space racing their way toward Earth, potentially making impact within three days. Once particles from this CME event hit Earth, electrical systems in orbit, in the sky and on...

Sun Erupts With Two CMEs In One Day
2013-03-14 14:15:10

Brett Smith for redOrbit.com - Your Universe Online Earlier this week the sun twice ejected large amounts of solar material during two coronal mass ejections (CMEs) in a 12-hour period, according to a NASA report. The CMEs are not expected to significantly impact Earth. The first CME began at 8:36 p.m. EDT on March 12, 2013. The solar material was directed toward three NASA spacecraft, Spitzer, Kepler and Epoxi. Two of the crafts, Spitzer and Kepler, are in an Earth-like orbit around...

Flare, Ejection And Rain All Caught In Spectacular Solar Show

[Watch Video: Fiery Looping Rain On The Sun] Lee Rannals for redOrbit.com — Your Universe Online An eruption on the sun can be a beautiful, monstrous event, and NASA's Solar Dynamics Observatory (SDO) has helped to bring these dangerous, yet breathtaking events right to our computer screens. On July 19, 2012, the sun erupted in a solar flare, ejecting material called a coronal mass ejection (CME), creating a loop in the sun's atmosphere known as the corona. This moderately...

Earth-Directed CME Released Associated With A Long Duration Solar Flare
2013-02-11 08:01:42

NASA On Feb. 9, 2013 at 2:30 a.m. EST, the sun erupted with an Earth-directed coronal mass ejection or CME, associated with a long duration C2.4-class flare. Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory (STEREO) and ESA/NASA´s Solar and Heliospheric Observatory, show that the CME left the sun at speeds of around 500 miles per second, which is a fairly typical speed for CMEs. Historically, CMEs at this speed are usually...

Two Coronal Mass Ejections Produced By The Sun On Feb 5

NASA [ Watch The Video ] In the evening of Feb. 5, 2013, the sun erupted with two coronal mass ejections or CMEs that may glance near-Earth space. Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory (STEREO) and ESA/NASA´s Solar and Heliospheric Observatory, show that the first CME began at 7 p.m. EST and left the sun at speeds of around 750 miles per second. The second CME began at 10:36 p.m. EST and left the sun at speeds of...

Sun Erupted With A Coronal Mass Ejection

NASA [ Watch The Video ] On Jan. 31, 2013 at 2:09am EST, the sun erupted with an Earth-directed coronal mass ejection or CME. Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory (STEREO) and ESA/NASA´s Solar and Heliospheric Observatory, show that the CME left the sun at speeds of around 575 miles per second, which is a fairly typical speed for CMEs. Historically, CMEs at this speed are mild. Not to be confused with a solar...

Sun Unleashes Two Coronal Mass Ejections On January 23

[ Watch the Video: SOHO Captures CME On January 23, 2013 ] Lee Rannals for redOrbit.com - Your Universe Online The sun showed off its strength on Wednesday with two coronal mass ejections (CME), observed by both NASA and the European Space Agency instruments. NASA's Solar Terrestrial Relations Observatory (STEREO) and both of the space agencies' Solar and Heliospheric Observatory (SOHO) helped to unveil the activity during the solar maximum cycle. The CME seen at 9:55 a.m. EST on...

Karen C. Fox, NASA's Goddard Space Flight Center, Greenbelt, Md. On Jan. 13, 2013, at 2:24 a.m. EST, the sun erupted with an Earth-directed coronal mass ejection or CME. Not to be confused with a solar flare, a CME is a solar phenomenon that can send solar particles into space and reach Earth one to three days later. Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory (STEREO) and the ESA/NASA mission the Solar and Heliospheric...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
