What is happening to the sun?

Every morning I check the sunspot activity before I go to work. This morning I noticed for the first time that the solar flux has been dropping over the past couple of months. This is the energy output of the sun.

Below are two pictures from here

I have watched this indices for several years and it is normally around 70 over the last couple of years but goes up when there are sunspots. But this stretch of sunspots (34 days) seems to be bringing even lower solar output. Below is what it was like back in the 45 day spotless streak of April and May.
