Solar Flares Today!

Below you will find the most recently available image from NASA's Solar Dynamics Observatory (SDO) which shows us the Sun in the 131 Ångström wavelength. This wavelength is best used to observe solar flares. A solar flare will show up as a very distinct bright white flash on this image. A strong solar flare that takes place around a reasonable earth-facing sunspot region could potentially release a cloud of solar plasma (coronal mass ejection) that will produce aurora here at Earth later on. Finally you will find a 24-hour solar flare plot using data from GOES-15.

The above plot is similar to the X-Ray Flux post earlier today. It shows that the X-Ray spikes often represent Flares from the Sun.
