Solar cycle 16 was the sixteenth solar cycle since 1755, when extensive recording of solar sunspot activity began.〔Kane, R.P. (2002). "(Some Implications Using the Group Sunspot Number Reconstruction )". ''Solar Physics'' 205(2), 383-401.〕〔(【引用サイトリンク】 url=http://www.spacetoday.org/SolSys/Sun/Sunspots.html )〕 The solar cycle lasted 10.1 years, beginning in August 1923 and ending in September 1933. The maximum smoothed sunspot number (monthly number of sunspots averaged over a twelve-month period) observed during the solar cycle was 78.1 (April 1928), and the minimum was 3.5.〔SIDC Monthly Smoothed Sunspot Number. "()"〕 There were a total of 568 days with no sunspots during this cycle.〔Spotless Days. "()"〕〔What's Wrong with the Sun? (Nothing) more information: Spotless Days. "()"〕〔Solaemon's Spotless Days Page. "()"〕 Newspaper reports during this period note effects on telegraph systems, but also (in March 1924, January 1926, October 1926, and October 1927) on radio transmission.〔http://www.solarstorms.org/SRefStorms.html〕 ==See also== *Solar variation *List of solar cycles 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Solar cycle 16」の詳細全文を読む スポンサード リンク
