Solar cycle 8 : ウィキペディア英語版 | Solar cycle 8
Solar cycle 8 was the eighth 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 9.8 years, beginning in November 1833 and ending in July 1843. The maximum smoothed sunspot number (monthly number of sunspots averaged over a twelve-month period) observed during the solar cycle was 146.9 (March 1837), and the minimum was 10.6.〔SIDC Monthly Smoothed Sunspot Number. "()"〕 Solar cycle #8 ended in 1843, the year that Heinrich Schwabe discovered the sunspot cycle.〔Claudio Vita-Finzi.
