Today there is a very large sunspot that has been described as large enough to see with the naked eye at sunset or sunrise. I would not recommend looking at the Sun unless you have proper viewing equipment.
This picture is one of a couple of quick shots of the Sun from earlier today. The large sunspot is rather distinct. The camera particulars are on the picture. I use a screw-in 58mm solar filter on my DSLR camera, a Canon Rebel T3i. The filter shows the Sun in visible light and comes from Thousand Oaks Optical and is reasonably priced. If you have never imaged the Sun before this is one path in that direction.
Reminder: On a clear day you can see 92,955,807.26 miles (149,597,870.69 km)
