Powerful solar flare measuring X2.1 erupts from Region 2297

Powerful solar flare measuring X2.1 erupts from Region 2297

A major solar flare measuring X2.1 (R3-Strong radio blackout) erupted from Region 2297 at 16:22 UTC on March 11, 2015. The event started at 16:11 and ended at 16:29 UTC.

A Type II (estimated velocity 1 461 km/s) and IV radio emissions were associated with the event. Type IV emissions occur in association with major eruptions on the Sun and are typically associated with strong Coronal Mass Ejections (CMEs) and solar radiation storms.

Additionally, a 10cm radio burst lasting 3 minutes, with peak flux of 160 sfu was also associated with the event. A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.

This region has 'beta-gamma-delta' magnetic configuration and is capable of producing more strong eruptions on the Sun.

It already produced partially Earth-directed CMEs over the last couple of days so it is possible that this eruption has an Earth-directed component.

Sunspots

Region 2297 is still the only numbered sunspot region on the Earth side of the Sun. It maintains its size and complex magnetic structure.

Update:

SDO/AIA imagery observed ejecta leaving the flare location in a mostly easterly direction.

Update #2:

Due to an extended outage of SOHO LASCO coronagraph imagery, accurate analysis of any CMEs associated with the X2.1 solar flare from March 11 is degraded, at best. However, the presence of the Type II radio sweep combined with SDO/AIA 304 imagery indicated there was likely a CME associated with the X2 flare with at least a portion of the plasma cloud directed at Earth, SWPC said in their Forecast Discussion issued March 12, 2015 at 12:30 UTC.

And a eclispe around the corner as well

I would say:"Watch carefully the two coming days" but knowing almost with certainty that what we see on SOHO images displayed to the public aren't "live broadcast"but probably happened since two days, (for national defense security THEY would say!), so nothing to worry about, this spot is already rotating far from earth. If a kill_shot occurs, you will not know it from NASA but the red sky will tell you, and it will be already late to do anything about it, the best that you can do is ALWAYS have extra food ,extra water and a PLAN.

wow tht is crazy i felt an electric shock going thru my arm and my soul twin flame is a reincarnated God of the sun..well he got mad and really tired today hasnt slept in two days. and i am the godess of the divine. we can actually feel the same physically, mentally and emotionally. we think the same things and can read each others mind!! not on demand though but happens everyday. these are our signs and birthday cusps (he was suppose to be born on Dec 21, 1978..but was late)..HIS: 1-1-1979, saggitarius/ capricorn, fire/earth element...MINE: 5-21-1991, gemini/taurus cusp, air/earth element. We have only been knowing each other 6 weeks and all these strange things are going on we can feel vibes coming off of each other.. i read tht we are the two witnesses... the last prophecies... everything i read about us has already came to light and still progressing. if you have any information please let me know. thankyou!
