Sun spots

The current active phase of the Sun continues apace with another large sunspot group crossing the face of the sun over the last few days.  I took this picture yesterday just before sunset which shows AR1520, the large grouping at the top of the picture with 1519 & 1521 the two at the very bottom.

Edit:At 16:53 UT on the 12th Jul sunspot AR1520 unleashed an X class solar flare in the direction of Earth. http://www.spaceweather.com has further details.
