Cycle 24 activity in January was low. Cycle 24 solar maximum is probably about 18 months away. The January sunspot number and the F10.7 flux are following the NASA forecast. The very low Ap index seems confirm that this cycle is likely to be much less active than Cycle 23. See the charts below, all courtesy of NOAA/SWPC. (click on charts to enlarge)
