태양이 거대한 X-화염을 분출했고, 그것이 지금 우리들 쪽으로 오고 있다

THE SUN HAS JUST UNLEASHED A GIGANTIC X FLARE AND IT'S NOW HEADING OUR WAY

FIRST X-FLARE OF THE NEW SOLAR CYCLE: Sunspot 1158 has unleashed the strongest solar flare in more than four years. The eruption, which peaked at 0156 UT on Feb. 15th, registered X2 on the Richter scale of solar flares. NASA's Solar Dynamics Observatory recorded an intense flash of extreme ultraviolet radiation,...

이것은 이전의 화염들이 총알이라면 미사일 급에 해당한다고 합니다.

이것이 오늘 뉴스보도에 의하면 17일에 지구로 도착한다고 하는데,그것이 지구내부의 운동을 자극해서 뉴마드리드의 단층 운동을 촉발시킬지도 모르겠습니다. 필수품 비축을 미루지 마세요..

COMET FLYBY: Last night, Feb. 14th, NASA's Stardust-NExT spacecraft flew past the icy core of Comet Tempel 1 at a distance of only 181 km. Mission contollers say the flyby appears to have been a success and images are being beamed back to Earth now. Tune into nasa.gov for close-ups.

FIRST X-FLARE OF THE NEW SOLAR CYCLE: Sunspot 1158 has unleashed the strongest solar flare in more than four years. The eruption, which peaked at 0156 UT on Feb. 15th, registered X2 on the Richter scale of solar flares. NASA's Solar Dynamics Observatory recorded an intense flash of extreme ultraviolet radiation, circled below:

X-flares are the strongest type of solar flare, and this is the first such eruption of new Solar Cycle 24. In addition to flashing Earth with UV radiation, the explosion also hurled a coronal mass ejection (CME) in our direction. The expanding cloud may be seen in this movie from NASA's STEREO-B spacecraft. Geomagnetic storms are possible when the CME arrives 36 to 48 hours hence. Stay tuned for updates.

SWEET AURORAS: Last night, as predicted, a gust of solar wind hit Earth's magnetic field, sparking bright Valentine's auroras around the Arctic Circle. Øystein Lunde Ingvaldsen sends this picture of the sweet lights over Bø in Vesterålen, Norway:

"It was a short but beautiful blast of Northern Lights," says Ingvaldsen. "Perhaps this is a preview of things to come later this week." Indeed, a series of CMEs en route to Earth from exploding sunspot 1158 are expected to arrive on Feb. 15th-17th, prompting bright displays at even lower latitudes. Sky watchers should be alert for auroras.

Near Earth Asteroids

Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.

On February 15, 2011 there were 1198 potentially hazardous asteroids.

Recent & Upcoming Earth-asteroid encounters:

Asteroid	Date(UT)	Miss Distance	Mag.	Size
2011 CZ3	Feb 10	2.5 LD	--	24 m
2011 CD66	Feb 13	7.2 LD	--	18 m
2011 CL50	Feb 19	6.2 LD	--	13 m
2003 YG118	Feb 20	67.7 LD	--	1.8 km
2000 PN9	Mar 10	45.5 LD	--	2.6 km
2002 DB4	Apr 15	62.5 LD	--	2.2 km
2008 UC202	Apr 27	8.9 LD	--	10 m
2009 UK20	May 2	8.6 LD	--	23 m
2008 FU6	May 5	75.5 LD	--	1.2 km
2003 YT1	May 5	65.3 LD	--	2.5 km
2002 JC	Jun 1	57.5 LD	--	1.6 km
2009 BD	Jun 2	0.9 LD	--	9 m

Notes: LD means "Lunar Distance." 1 LD = 384,401 km, the distance between Earth and the Moon. 1 LD also equals 0.00256 AU. MAG is the visual magnitude of the asteroid on the date of closest approach.
