Solar flares

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. Below this image from NASA's Solar Dynamics Observatory (SDO) you will also find two buttons to watch footage from the GOES satellites. This is a good alternative in case there are problems with SDO. Finally you will find a 24-hour solar flare plot using data from the primary GOES satellite. You can zoom in on this plot by selecting a time period that you wish to view and even export the graph as a JPG, PDF, SVG or PNG file.
