I took this picture of the Sun with a small refractor and a solar filter earlier today. The giant sunspot group on the left has a dark core easily big enough to swallow the Earth. Astronomers have labelled it AR2192. At around 0500UT on Sunday AR2192 unleashed a powerful X-class flare. It wasn't Earth directed. The rotation of the Sun will carry AR2192 towards the solar meridian in a few days and any flares of that magnitude are very likely to create chances to see the aurora soon after that.
