Sunspot at Sunset
Sunspots in the Sun appear very small and dainty when we are looking at them but they are in fact huge and can span miles. This particular sunspot was so large is could be viewed with the naked eye. This picture was taken from Swiss skies on January 5th. The sunspot showed an active region in which tornadoes or other storms could be occurring. On January 7th it produced a solar flare and a coronal mass ejection which then led to geomagnetic storms and an aurora on January 9th. Sunspots can also be very dense.
