Solar cycle 24 - Wikipedia
WEBSolar cycle 24 is the most recently completed solar cycle, the 24th since 1755, when extensive recording of solar sunspot activity began. [ 1 ][ 2 ] It began in December 2008 with a minimum smoothed sunspot number of 2.2, [ 3 ][failed verification] and ended in December 2019. [ 4 ]

Predictions of Solar Cycle 24: How are we doing?
WEBDec 16, 2015 · Given the wide range of the predictions for the amplitude of Solar Cycle 24 and the many methods that were used to produce them, we look forward to this cycle answering important questions about how to predict solar activity at the Earth and throughout the solar system.

WEBMany cycles are double peaked but this is the first in which the second peak in sunspot number was larger than the first. We are currently over seven years into Cycle 24. The current predicted and observed size makes this the smallest sunspot cycle since Cycle 14, which had a maximum smoothed sunspot number V2.0 of 107.2 in February of 1906.
Predictions of Solar Cycle 24: How are We Doing?
WEBJan 14, 2016 · Solar Cycle 24 is on track to have a below-average amplitude, peaking at an annual sunspot number of about 80. Our need for solar activity predictions and our desire for those predictions to be made ever earlier in the preceding solar cycle will be discussed.
