This is an image of the Sun showing the sunspot AR 12192, the largest sunspot of the solar cycle 2010 to 2020. This image was taken at solar maximum when the sun is most active during a cycle. It was imaged in October 2014 in Quezon City using a 4 in f/9 refractor and a Baader ND 5 solar filter. The textured surface of the Sun and a number of sunspots are visible in this photo. Never observe or image the Sun without the proper solar filters.
