I noticed on SpaceWeather.com that there are several solar flare alerts in connection with Sunspot number AR1520, now rounding the face of the sun. I went outside this afternoon and made this image of the solar plasma where a group of spots is clearly visible.
The scientists studying sunspots say that AR1520 could be capable of causing X-class flares which could disrupt power grids and radio communication on Earth. Click on the image to enlarge.
