MAGNIFICENT ERUPTION: On August 31st, a magnetic filament on the sun
erupted in spectacular fashion, producing a long-duration solar flare, a
coronal mass ejection (CME) and one of the most beautiful movies of an
explosion ever recorded by NASA's Solar Dynamics Observatory. The CME
propelled by the blast might deliver a glancing blow to Earth's magnetic
field in the days ahead. Check http://spaceweather.com for movies, forecasts and updates.

SUNGRAZING COMET SURVIVES: Sungrazing Comet Lovejoy has confounded the experts and survived its close encounter with the sun. Last night, NASA's Solar Dynamics Observatory recorded amazing movies of the comet entering and exiting the sun's atmosphere. Comet Lovejoy's scorched remnant is now receding from the sun in full view of the Solar and Heliospheric Observatory. Visit http://spaceweather.com for the latest movies and discussion.

Magnificent Solar Flare on June 7th
Source - Space Weather News for June 7, 2011: http://spaceweather.com
MAGNIFICENT ERUPTION: This morning around 0641 UT, magnetic fields above sunspot complex 1226-1227 became unstable and erupted. The blast produced an M2-class solar flare, an S1-class radiation storm, and a massive CME. A recording of the blast from NASA's Solar Dynamics Observatory ranks as one of the most beautiful and dramatic movies of the SDO era. Must-see movies at http://spaceweather.com
AURORA WATCH: High-latitude sky watchers in both hemispheres should be alert for auroras during the late hours of June 8th or 9th when a CME from today's eruption could deliver a glancing blow to Earth's magnetic field. Aurora alerts are available from http://spaceweatherphone.com (voice) or http://spaceweathertext.com (text).

SDO Video: X2 C2 Combo - Feb. 15, 2011
On Feb. 15, 2011 an X2 class x-ray solar flare was observed by the Solar Dynamics Observatory. Below is a video from the SDOmission2009 YouTube channel of the of the eruption:
Here is the description of the video from the SDOmission2009 page:
"The X2 flare of Feb. 15, 2011 seen by SDO (in extreme ultraviolet light) enlarged and superimposed on SOHO's coronagraph that shows the faint edge of a "halo" coronal mass ejection as it races away from the Sun. The video covers about 11 hours."

NASA SDO Video: Dazzling Duo
Below is the most recent video from SDOmission2009:
The vdeo was posted on 02/11/2011. Here is the description of the video from the YouTube page:
"As SDO observed in extreme ultraviolet light, a pair of active regions put on quite a show over a three-day period (Feb. 7-10, 2011). The magnetic field lines above the regions produced fluttering arcs waving above them as well as a couple of flares. Another pair of smaller active regions emerges and trails behind the larger ones."

DODGING PLASMA BULLETS: Old sunspot complex 1147-1149 is emerging over the sun's eastern limb for a second pass across visible face of the sun--and it is firing 'plasma bullets' into space. So far none of the eruptions has come our way, although this could change as the region turns toward Earth.

Double Blast on the Sun
Source - Space Weather News for Jan. 28, 2011: http://spaceweather.com
DOUBLE BLAST: This morning, a spectacular double eruption on the sun produced the strongest solar flare of the year so far (an M1-class event). Plasma clouds produced by the event are expected to miss Earth, so no geomagnetic storms are in the offing. Today's edition of http://spaceweather.com highlights movies captured by SOHO and the Solar Dynamics Observatory.
STRANGE LIGHT PILLARS: A photographer has recorded extraordinary pillars of light shooting into the night sky from a corn mill in Nebraska. The tall luminous columns were capped with nested V-shaped tops that distinguish them from ordinary urban light pillars. Check http://spaceweather.com for must-see photos and an explanation of the icy phenomenon.

Sun Twister Eruption
Source - Space Weather News for Oct. 28, 2010: http://spaceweather.com
SUN TWISTER: Earlier today, NASA's Solar Dynamics Observatory (SDO) recorded a spectacular eruption on the sun's northeastern limb. An unstable magnetic filament hundreds of thousands of kilometers long pirouetted and launched a fragment of itself into space. Earth was not in the line of fire, but the SDO movie is worth seeing anyway. Visit http://spaceweather.com for cinema.
ASTEROID FLYBY: Asteroid 2003 UV11 will fly past Earth on Oct. 29th and 30th at a distance of only 1.2 million miles. Experienced amateur astronomers should have little trouble photographing the 600-meter wide space rock as it glides through the constellation Pegasus on Friday night, glowing about as brightly as a 12th magnitude star. Observers in North America and Europe are favored. Check http://spaceweather.com for ephemerides and more information.

SPECTACULAR ERUPTION: Just as sunspot 1105 was turning away from Earth on Sept 8th, the active region unleashed a spectacular eruption of plasma and extreme ultraviolet radiation. Earth was not in the line of fire--this time. Must-see movies from the Solar Dynamics Observatory and other spacecraft are highlighted on today's edition of http://spaceweather.com.
SPACECRAFT FLYBY ALERT: This is a good week for satellite watchers in the USA and Canada. Both the International Space Station and the US Air Force X-37B space plane are making a series of favorable passes over North American towns and cities. The spacecraft are easy to find using our Simple Satellite Tracker--an app for iPhones and Android. Visit http://simpleflybys.com for downloads and more information.

Solar eruption misses Earth, auroras likely anyway
SOLAR ACTIVITY: On Sept. 4th around 1600 UT, a magnetic filament erupted, hurling a bright coronal mass ejection (CME) off the sun's northwestern limb. Today's edition of http://spaceweather.com features a close-up view of the blast from NASA's Solar Dynamics Observatory. The CME is not expected to hit Earth. Nevertheless, auroras are possible in the nights ahead. A solar wind stream flowing from a coronal hole is heading our way, due to arrive on Sept. 5th or 6th. NOAA forecasters estimate a 50% chance of high-latitude geomagnetic activity when the solar wind hits. With the approach of northern autumn, Arctic nights are getting dark again--dark enough to see the Northern Lights. People in Alaska, Canada and Scandinavia should keep an eye on the night sky this weekend.

Complex Eruption on the Sun Sends CME toward Earth
Source - Space Weather News for August 1, 2010: http://spaceweather.com
GLOBAL ERUPTION: During the early hours of August 1st, NASA's Solar Dynamics Observatory recorded a complex global disturbance on the Earth-facing side of the sun. Most of the sun's northern hemisphere was involved in the event, which included a long-duration C3-class solar flare, a "solar tsunami," and a massive filament eruption. As a result of these blasts, a coronal mass ejection (CME) is heading toward Earth. High-latitude geomagnetic storms and auroras are possible when the cloud arrives a few days hence.
