Summary

DescriptionSolar Cycle Prediction.gif	English: The prediction for Sunspot Cycle 24 as of December 2017 gives a smoothed sunspot number V2.0 maximum of about 101 in late 2013. The smoothed sunspot number V2.0 reached a peak of 116.4 in April 2014. This will probably become the official maximum. This second peak surpassed the level of the first peak (98.3 in March 2012). Many 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 predicted and observed size as of December 2017 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.
