Astronomers at Kitt Peak National Observatory in Arizona noted recently that a sunspot had grown so large it could be seen without using a solar telescope. Known as Sunspot 1089, spaceweather.com reported that scientist "spotted it" as the sun set over Kitt Peak (you can sort of spot it in the lower left side of this posted photo). Huge sunspots do appear from time to time. In 2004 NASA noted a sunspot 20 times the size of Earth. NASA also noted a large number of solar events occurred in the fall of 2003 when about 17 major flares erupted on the sun.
