Solar activity: Sunspot Has Produced M-Class Flares, But No CMEs

Inserito da

The sun unleashed an M4.7 class flare at 8:32 EDT on May 9, 2012 as captured here by NASA’s Solar Dynamics Observatory. The flare was over quickly and there was no coronal mass ejection associated with it. This image is shown in the 131 Angstrom wavelength, a wavelength that is typically colorized in teal and that provided the most detailed picture of this particular flare. Credit: NASA/SDO. Due to current issues on the SOHO spacecraft, the LASCO instrument was not taking data during this event. This

instrument is used to develop the near real-time coronal mass ejections alerts. The STEREO beacon data is now coming online and indicates a possible small coronal mass ejection. A preliminary indication of its direction indicates a low likelihood of any geomagnetic storms at Earth. A particularly large and complex sunspot appeared over the left limb of the sun on Saturday, May 5, beginning its two-week trek across the face of the star in conjunction with the sun’s rotation. The sunspot, dubbed Active Region 1476, has so far produced seven M-class flares and numerous C-class flares, including two M-class flares on May 9, 2012 that peaked at 8:32 EDT and 10:08 EDT. These flares were all short-lived and there were no associated coronal mass ejections, so we do not expect any geomagnetic storms at Earth. The upper left corner of this image of the sun, shows the biggest and most complex sun spot visible on the sun as of May 9, 2012. It has produced 7 M-class flares so far, but has not produced any coronal mass ejections that could cause geomagnetic storms near Earth. Credit: NASA/SDO. News from:NASA
