We are now in period called Solar Cycle 24 which started in January 8, 2008 and it is the 24th solar cycle since 1755, when recording of solar sunspot activity began. The solar cycle is the periodic change in Sun’s activity (including changes in the levels of solar radiation and ejection of solar material) and appearance visible in changes in the number of sunspots, flares, and other visible manifestations. Solar cycles have a duration of about 11 years. NASA predicts that solar cycle 24 will peak in early or mid 2013 with about 59 sunspots. This would make it the least active cycle in the past one...

Solar cycles have a duration of about 11 years.

NASA predicts that solar cycle 24 will peak in early or mid 2013 with about 59 sunspots. This would make it the least active cycle in the past one hundred years. The International Space Environment Service predicts the cycle to peak at 90 sunspots in May 2013.
