Spring fling: Sun emits a mid-level flare

UPDATE: 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 ...

Solar storm near Earth caused by fast CME

On March 17, 2013, at 1:28 a.m. EDT, the coronal mass ejection (CME) from March 15 passed by NASA's Advanced Composition Explorer (ACE) as it approached Earth. Upon interacting with the giant magnetic bubble surrounding Earth, ...

Earth-directed CME released by long duration solar flare

(Phys.org)—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 ...

Solving a mystery of the Sun's corona

(Phys.org)—The corona of the sun is the hot (over a million kelvin), gaseous outer region of its atmosphere. The corona is threaded by intense magnetic fields that extend upwards from the surface in braids that are twisted ...

NASA sees a coronal mass ejection erupt from the sun

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 ...

Sun shoots out two coronal mass ejections

On Jan. 23, 2013, at 9:55 a.m. 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) ...

Continuing Thanksgiving eruptions on the Sun
