INCOMING CMEs: One and perhaps two CMEs are expected to hit Earth's magnetic field today. Of particular interest is a CME launched toward Earth by a powerful M8-class eruption on March 10. Forecasters say the cloud could spark minor to severe geomagnetic storms when it arrives on March 11-12. High-latitude sky watchers should be alert for auroras tonight. Check http://spaceweather.com for updates.
WHAT DOES A SOLAR FLARE SOUND LIKE? Saturday's M8-class flare hit Earth with a burst of strong shortwave radio emissions. Today's edition of Spaceweather.com features an audio recording of the blast captured by an amateur astronomer in New Mexico.

Big Sunspot Unleashes X-flare
Source - Space Weather News for March 5, 2012: http://spaceweather.com
STRONG SOLAR ACTIVITY: Big sunspot AR1429, which emerged over the weekend, is crackling with strong flares. This morning the active region produced an X1-class eruption and a bright coronal mass ejection (CME). The CME appears set to deliver a glancing blow to Earth's magnetic field in the days ahead, possibly sparking geomagnetic storms. Stay tuned to http://spaceweather.com for images and updates.

Strong Solar Activity Could Spark Auroras
Source - Space Weather News for Sept. 7, 2011: http://spaceweather.com
STRONG SOLAR ACTIVITY: On Sept. 6th, active sunspot 1283 produced two major eruptions including an impulsive X2-class solar flare. The blasts hurled a pair of coronal mass ejections (CMEs) toward Earth, which could spark geomagnetic activity when they arrive on Sept. 8-10.
High-latitude sky watchers should be alert for auroras in the nights ahead. Check http://spaceweather.com for images and updates.

Massive Prominence Eruption / CME June 7 , 2011
Source: SolarWatcher on Jun 7, 2011
Here is a beautiful video of today's Solar Flare / CME. Below is the description from the SolarWatcher post:
"M-FLARE AND RADIATION STORM: 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"

Dodging Plasma Bullets

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. Today's edition of http://spaceweather.com features a must-see movie from the Solar Dynamics Observatory.

Bright X-ray Solar Flare
Source - Space Weather News for Nov. 6, 2010: http://spaceweather.com
BRIGHT SOLAR FLARE: Active sunspot 1121 has just unleashed one of the brightest x-ray solar flares in several years, an M5.4-class eruption at 15:36 UT on Nov. 6th. Radiation from the flare created a wave of ionization in Earth's upper atmosphere that altered the propagation of low-frequency radio waves. There was, however, no bright CME (plasma cloud) hurled in our direction, so the event is unlikely to produce auroras in the nights ahead. Visit http://spaceweather.com for a movie of the eruption and more information about this increasingly active sunspot.

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.

Bright Fireball Rivals the Harvest Moon + a Big Solar Event
Source - Space Weather News for Sept. 22, 2010: http://spaceweather.com
GLOBAL ERUPTION ON THE SUN: This morning between 0230 UT and 0600 UT, the northern hemisphere of the sun erupted in a tumult of activity. There was a solar flare, a coronal mass ejection, and at least two dark magnetic filaments lifting off the stellar surface. The event appears to be a smaller-scale version of the global blast in early August that sparked auroras over some US states. As before, NASA spacecraft recorded the action in detail. Visit http://spaceweather.com for movies and updates.
SOUTHWESTERN FIREBALL RIVALS THE HARVEST MOON: Last night, sky watchers in the southwestern United States witnessed a brilliant fireball. It was almost as bright as the full Harvest Moon and caused a loud sonic boom over parts of New Mexico. A movie of the event is highlighted on today's edition of http://spaceweather.com.

Arctic Aurora Watch
Source - Space Weather News for Sept. 12, 2010: http://spaceweather.com
ARCTIC AURORA WATCH: A magnetic filament on the sun erupted during the late hours of Sept. 10th, hurling a bright coronal mass ejection (CME) into space. The CME is not heading directly for Earth, but the cloud's southern flank could deliver a glancing blow to our planet's magnetic field on Sept. 12th or (more likely) Sept. 13th. People in Alaska, Canada, Iceland, Greenland and Scandinavia should be alert for Northern Lights in the nights ahead. Check http://spaceweather.com for updates and movies of the eruption that prompted this alert.

Spectacular Eruption: Earth dodges another bullet from the Sun
Source - Space Weather News for Sept. 9, 2010: http://spaceweather.com
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.

Incoming CME could spark high-latitude auroras
Source - Space Weather News for August 9, 2010: http://spaceweather.com
INCOMING CME: The solar eruption of August 7th might affect Earth after all. Newly-arriving data from the Solar and Heliospheric Observatory (SOHO) show a CME heading our way with a significant Earth-directed component. High-latitude sky watchers should be alert for auroras when the cloud arrives on August 10th. A movie of the CME is featured on today's edition of http://spaceweather.com.
EARLY PERSEID METEORS: The Perseid meteor shower doesn't peak until August 12th, but already late-night sky watchers are seeing a nice display of shooting stars. Observers are counting as many as 20 Perseids per hour from dark sky sites, a number that could increase 3- to 5-fold before the week is over. Visit http://spaceweather.com for more information.
