Pretty low! Here are the monthly average sunspot numbers by year and month from NASA's Marshall Space Flight Center. The Sun is in an extended solar minimum, and we had expected the sunspot cycle to pick up last year some time.
But while the Sun is very quiet, this isn't unheard of. Unusual, yes.

∙ 14y agoThere were very few sunspots visible from the beginning of 2009 through the end of November, a total of 260 sunspot-less days. It was only in December that the Sun began to be more active. The solar activity since December 2009 continues to be well below average for the beginning of the solar cycle, but appears to no longer be pegged at zero.
