NASA SDO - X1.9 Class Solar Flare, November 3, 2011.mov

"Bad Boy" active region 1339 continues to flare. At 20:27 UT a solar flare peaked at X1.9. X-class flares are pretty massive and are major events that can trigger planet-wide radio blackouts and long-lasting radiation storms. The location of this sunspot/active region is still not quiet Earth directed. Credit: NASA SDO

NASA SDO - X2-class Solar Flare, January 27, 2012

Our "bad boy" sunspot 1402 continues to unleash flares. At 18:37 UT this active region produced the largest category of flares; an X-class flare. It measured X2 to be exact. Since this active region is rotating over the limb of the Sun the eruption was not Earth directed. But energetic protons accelerated by the blast are now surrounding our planet and a S1-class radiation storm is in progress. S1-class is the lowest of 5 (S1 to S5) and has no biological impact, no satellite operations are impacted but some minor impact on HF radio is experienced. Credit: NASA SDO

NASA SDO - X1.1 Solar Flare, March 5, 2012

After several days of a quiet Sun, the solar activity is now high again. Big sunspot AR1429, which emerged on March 2nd, is crackling with strong flares. This morning brought the strongest so far--an X1-class eruption on March 5th at 0413 UT. This flare propelled a bright Coronal Mass Ejection into Space, which will probably miss Earth, but hit Mercury and Venus. Even if this CME misses, high-latitude sky watchers should still be alert for auroras in the nights ahead. An M2-class eruption from the same sunspot on March 4th produced another, wider CME that might yet intersect Earth. The cloud is expected to deliver a glancing blow to our planet's magnetic field on March 6th at 04:30 UT (+/- 7 hr). Take a look at the forecast from our friends at the NASA Goddard Space Weather Lab: http://iswa.gsfc.nasa.gov/downloads/20120305_085600_anim.tim-den.gif Credit: NASA SDO

NASA SDO - X5.4-class Solar Flare, March 7, 2012

Right at midnight UT time the active region 1429 unleashed a powerful X5.4-class solar flare. X-class flares are the strongest of the flares. They are major events that can trigger planet-wide radio blackouts and long-lasting radiation storms. It appears that right after the large X5.4 flare another slightly lower, X1 flare (5 times smaller) occurred. You can clearly see a wave going across the Sun. We are still gathering data and the Space Weather Forecast Lab will be having updates available soon. Credit: NASA SDO

NASA SDO - X-class Solar Flares & Solar Tsunami, March 7, 2012

On March 7, 2012 just a few minutes after midnight UT time the active region (AR11429) unleashed two strong X-class flare. The first, X5.4-class, showed a very bright flare, the second right after, X1-class, hurled a second coronal mass ejection into Space. Also seen can be a wave going across the Sun at approx. 1,000,000 mph - also known as a Solar Tsunami. Here are various views of this events over a couple of hours, including some close-up views of the Sunspot 1429. Credit: NASA SDO & Dr. A. Kosovichev, HMI
