Large Sunspot Today

There is a large sunspot visible today. It is about the same size that Venus will appear during the transit. It is an excellent chance to practice your photographic set up in preparation for the transit of Venus this June.

Sunspots are darker areas visible against the solar disk. The darker areas are still quite bright, just not nearly as bright as the photosphere - the part of the Sun you normally 'see'. Hence they appear dark.
