The 21st solar cycle is characterized in terms of variations in sunspots, solar radio noise, EUV emission, and episodic phenomena. The data are presented in tables and graphs and compared with measurements obtained during the first years of cycle 22 (beginning September 1986). On the basis of its rapid rise, it has been predicted that cycle 22 will have an amplitude slightly greater than that of the largest recorded cycle (19), with sunspot numbers of about 200 and radio flux F(10.7) of about 250. Estimates based on observations of the end of cycle 21, however, are somewhat lower.
