ALMOST-X FLARE AND CME: This morning, Jan. 23rd around 0359 UT, big sunspot 1402 erupted, producing a long-duration M9-class solar flare. The explosion's M9-ranking puts it on the threshold of being an X-flare, the most powerful kind. NASA's Solar Dynamics Observatory captured the flare's extreme ultraviolet flash:
The Solar and Heliosphere Observatory (SOHO) and the STEREO-Behind spacecraft have both detected a CME rapidly emerging from the blast site. Analysts at the Goddard Space Weather Lab estimate a velocity of 2200 km. There is little doubt that the cloud is heading in the general direction of Earth. A preliminary inspection of SOHO/STEREO imagery suggests that the CME will deliver a strong glancing blow to Earth's magnetic field on Jan. 24-25 as it sails mostly north of our planet. Stay tuned for updates.Solar flare alerts

A powerful solar eruption is expected to blast a stream of charged particles past Earth on Tuesday, as the strongest radiation storm since 2005 rages on the sun.
NASA's Solar Dynamics Observatory caught an extreme ultraviolet flash from a huge eruption on the sun overnight (10:59 p.m. ET Sunday, or 0359 GMT Monday), according to SpaceWeather.com.
The solar flare spewed from sunspot 1402, a region of the sun that has become increasingly active lately. Several NASA satellites, including the Solar Dynamics Observatory, the Solar Heliospheric Observatory and the STEREO spacecraft, observed the massive sun storm.

At 11:18 AM on the cloudless morning of Thursday, September 1, 1859, 33-year-old Richard Carrington widely acknowledged to be one of England's foremost solar astronomers—was in his well-appointed private observatory
What Carrington saw was a white-light solar flare—a magnetic explosion on the sun," explains David Hathaway, solar physics team lead at NASA's Marshall Space Flight Center in Huntsville, Alabama.
Even more disconcerting, telegraph systems worldwide went haywire. Spark discharges shocked telegraph operators and set the telegraph paper on fire. Even when telegraphers disconnected the batteries powering the lines, aurora-induced electric currents in the wires still allowed messages to be transmitted.

X-RAY FLATLINE: With no sunspots actively flaring, the sun's X-ray output has flatlined. Solar activity should remain low for the next 24 hours with only a slight chance of M-class solar flares.

Slow-moving fireballs light up February skies
NASA wants people to check out the odd appearance and trajectory of the meteors
A strange breed of fireball is streaking through the skies this month, and NASA is urging folks on the ground to take notice.
February's fireballs — a term that describes meteors that appear brighter in the sky than Venus — aren't more numerous than normal, but their appearance and trajectory are odd, experts say.
"These fireballs are particularly slow and penetrating," meteor expert Peter Brown, a physics professor at the University of Western Ontario, said in a statement. "They hit the top of the atmosphere moving slower than 15 kilometers per second (33,500 mph), decelerate rapidly and make it to within 50 kilometers (31 miles) of Earth’s surface."
So far in February, NASA's All-Sky Fireball Network — which currently consists of six cameras set up in Georgia, Alabama, Tennessee and New Mexico — has photographed about half a dozen of these strange, slow-moving, deep-diving fireballs. They have ranged in size from basketballs to buses.
They all hail from the asteroid belt, but not from a single location in the asteroid belt," he said. "There is no common source for these fireballs, which is puzzling."
The "fireballs of February" have puzzled astronomers for decades. Skywatchers first noticed an increase in the number of deep-penetrating, bright meteors during February in the 1960s and '70s, Brown said.

RADIATION STORM HITS MARS ROVER: En route to the red Planet, Mars rover Curiosity has experienced the strongest solar radiation storm since 2005. The rover is okay. Researchers say this is a normal part of Curiosity's job as 'stunt double' for human astronauts

MAJOR SOLAR FLARE (UPDATED): Big sunspot AR1429 has unleashed another major flare. This one is the strongest yet, an X5-class eruption on March 7th at 00:28 UT. NASA's Solar Dynamics Observatory recorded the extreme UV flash:
This eruption hurled a bright CME into space, shown here in a movie from the Solar and Heliospheric Observatory. Analysts at the Goddard Space Weather Lab estimate that the CME will reach Earth on March 8th at 0625 UT (+/- 7 hr), possibly triggering a strong-to-severe geomagnetic storm. An animated forecast track shows the progression of the fast-moving cloud.
The flare also accelerated energetic protons toward Earth, triggering an S3-class solar radiation storm, in progress. Such a storm is mainly a nuisance to satellites, causing occasional reboots of onboard computers and adding noise to imaging systems.

STRONG FLARE, INCOMING CME: Departing sunspot AR1429 unleashed another strong flare on March 13th, an M7-class eruption that peaked around 1741 UT. Although the sunspot is no longer directly facing Earth, the blast will affect our planet. Analysts at the Goddard Space Weather Lab say a CME is en route to Earth, and its impact on March 15th at 06:20 UT (+/- 7 hours) could trigger minor to moderate geomagnetic storms. Also, protons accelerated by the flare are swarming around Earth, causing an S2-class radiation storm. Space weather alerts: text, phone.
BRIGHT COMET DIVES INTO RADIATION STORM: A bright comet is diving into the sun. It was discovered just last week by SOHO's SWAN instrument, so it has been named "Comet SWAN." The comet's death plunge ( or "swan dive") comes just as the sun has unleashed a strong flare and radiation storm around Earth.
BROKEN RECORD? The recent sustained activity of sunspot AR1429 has kept the Arctic Circle alight with auroras for almost two weeks
The Antarctic Circle has been similarly active.:pray

2012-03-13 22:10 UTC Parting Shot -- UPDATE
NOAA Region 1429 yielded an R2 (Moderate) Radio Blackout at 1741 UTC (1:41 p.m. EDT). The Solar Radiation Storm promptly reached S2 (Moderate) levels, but now should slowly decline. A CME also occurred that appears to be on a path not towards Earth. Updates as appropriate here.
