Active Region 1429 unleashed an X5.4-class solar flare early this morning at 00:28 UT, as seen in this image by NASA’s Solar Dynamics Observatory (AIA 304). The eruption belched out a large coronal mass ejection (CME) into space but it’s not yet known exactly how it will impact Earth — it may just be a glancing blow.

Solar flares are categorized by a scale according to their x-ray brightness. X is the strongest class, followed by M and then C-class. Within each class the numbers 1 through 9 subdivide the flares’ intensity.

A run-in with an X5-class flare is a major geomagnetic event that can cause radio blackouts on Earth and disrupt satellite operations, as well as intensify auroral activity.

The GOES satellite data for the March 7 flare is below:

The CME is expected to impact Earth sometime on the 8th or 9th. Check back here or at Spaceweather.com for updates on the storm (and any subsequent aurora photos!)

Also, check out the video below, assembled by the SDO team. Just after the X5.4-class flare another smaller X1-class flare occurred, sending a visible wave cross the Sun.

anyone have an umbrella I could borrow?

This flare is X5 flare will have impacts and supports our WeatherAction warnings for 6-7Mar re solar+earth weather + quake possible action in this period http://www.weatheraction.com/docs/WANews12No12.pdf

There’s no link between solar flares and quakes, beyond coincidence.

DrFlimmer March 7, 2012 at 2:28 PM

Indeed, and since earth is shaken many times per day by quakes finding such a coincidence is not that hard… but cause and effect are difficult to grasp sometimes for some folks.

see my second comment

Of course if there were a connection between solar flair activity and earthquakes there would be a 22 year periodicity to earthquakes. There is absolutely no statistical evidence for this.

Solar flares do not create earth quakes. Adult male Asian elephants do. Especially when the herd aligns with another herd.

Also a big CME weights about a loaded oil tanker top. We could easily cancel an CME earthquake by moving the oil tankers. Or realign the elephants.

Guys we are not just looking for any ‘coincidences’ but doing trials requiring (eg) M6+ quakes and so far have had success which others are examining which appears to be well beyond chance. Have a look at reports:

http://www.weatheraction.com/docs/WANews12No8.pdf
http://www.weatheraction.com/docs/WANews12No10.pdf
There has also been more coverage on Climate Realists

These are trials and results

Squidgeny you don’t know. Maybe you mean you know of nothing showing…

Anyone, and I mean anyone, can put text in a pdf and post it online and claim that its “science”.
Have these results been published in any reputable journal?

magnus.nyborg March 7, 2012 at 3:56 PM

Either way, this is promotion of personal theory, wich is against the posting criteria on this site.

Reported!

Apparently flares also affect sentence building….hmm im gonna do a study on correlation and claim its the truth…now thats science ;O)

Hassan_Eg March 7, 2012 at 11:31 PM

Guys Thats Right? About End OF The World?

Mass Vocals March 8, 2012 at 12:17 PM

i wonder does show that facts that a hell like place could have existence and we all be sent there ?
