When did solar cycle 23 end?
December 2008
Solar cycle 23 was the 23rd solar cycle since 1755, when extensive recording of solar sunspot activity began. The solar cycle lasted 12.3 years, beginning in August 1996 and ending in December 2008.

What will happen in Solar Cycle 25?
According to NOAA/NASA and international experts: “Cycle 25 will be similar in size to Cycle 24, preceded by a long, deep minimum. Solar Cycle 25 may have a slow start, but is anticipated to peak with solar maximum occurring between 2023 and 2026, and a sunspot range of 95 to 130.
What is the 22-year solar cycle?
Solar cycle 22 was the 22nd solar cycle since 1755, when extensive recording of solar sunspot activity began. The solar cycle lasted 9.9 years, beginning in September 1986 and ending in August 1996.
What is the 22 year cycle?
Upon the switch of the 11-year cycle, the magnetic poles at 30°–50° latitude in the southern and northern hemispheres revert to the opposite pole. Therefore, concerning the variation in the magnetic pole, the periodicity of the sunspot magnetic field is 22 years (twice that of 11 years), also known as the Hale cycle.
What is the solar cycle and when did it end?
The cycle featured a “double-peaked” solar maximum. The first peak reached 99 in 2011 and the second in early 2014 at 101. Cycle 24 ended in December 2019 after 11.0 years. This cycle lasted 11.6 years, beginning in May 1996 and ending in January 2008.
Is solar cycle 24 at its peak?
Solar Cycle 24 has been underway since 2011 and its peak was expected in 2013, but there have been fewer sunspots observed this year compared with the maximums of the last several cycles.
How often does the sun go through a cycle?
About every 11 years, the sun goes through a cycle defined by an increasing and then decreasing number of sunspots. Solar Cycle 24 has been underway since 2011 and its peak was expected in 2013, but there have been fewer sunspots observed this year compared with the maximums of the last several cycles.
What is the average length of solar cycle?
Solar cycles have an average duration of about 11 years. Solar maximum and solar minimum refer to periods of maximum and minimum sunspot counts. Cycles span from one minimum to the next. Samuel Heinrich Schwabe (1789–1875).
