摘要：

A long-term oscillatory variation has been detected in the relationship between F-region ionization and visible solar activity. The dominant component appears to be a cosine term of period equal to four sunspot-cycles. The last crossing of the zero line appears to have occurred during the 1947-1948 sunspot maximum, making that epoch of importance to statistical methods designed to remove this secular variation from ionospheric studies. © 1969.
