Hathaway, David H. (NASA Ames Research Center, Mail Stop: 258-5, Moffett Field, CA 94035 USA)
The solar cycle is reviewed. The 11-year cycle of solar activity is characterized by the rise and fall in the numbers and surface area of sunspots. A number of other solar activity indicators also vary in association with the sunspots including; the 10.7 cm radio flux, the total solar irradiance, th...
