Sun Erupts with Spectacular Flares

The Sun sent two flares yesterday from active region 1283. This video shows the second flare, at 6:12 p.m. EDT (2212 GMT) on Tuesday an even bigger flare than the M-class flare from early on Sept. 6, at about 0150 GMT. This was an X-class flare, major events that can trigger planet-wide radio blackouts and long-lasting radiation storms. The latest update says the CMEs could sail north of Earth, delivering a glancing blow to Earth’s magnetic field, and could arrive between September 8 -10. Spaceweather.com says high-latitude sky watchers should be alert for auroras in the nights ahead.

The image below was sent in to Universe Today by Monty Leventhal showing the type 4B Flare with an X-ray class of X-2 in active region 1283.

    Some great views of this solar eruption. There’s also a nice video of this event that combines imagery from SDO and SOHO in one frame to better illustrate the CME lifting off the Sun: http://www.youtube.com/watch?v=jKOMajibOIg&NR=1

    [Note the increasing amount of “snow” in the SOHO LASCO imagery, said to be caused by energetic protons generated by the flare.]

  2. Interesting but as news it was also interesting weeks ago when it was first posted.

      While there was some solar activity a few weeks ago as well, these two flares occurred yesterday, on Sept. 6th.

    During a large geomagnetic solar storm the northern lights can sometimes be observed far away from the arctic regions, like from New England, Michigan or Washington State, or even further south.

    A short HD film of what the northern lights then look like can be seen on http://www
