Weird 66 Hr Cyclic Solar Wind

Hi all,

I thought I'd ask a question:

If you look at the following:

www.sel.noaa.gov...

www.sel.noaa.gov...

You can see that the solar winds hitting us are coming in 66 hour cycles. I know CME's produce solar winds but to experience incoming cyclic solar winds seems a bit weird...

Equidistant sunspots?

Anyone know ?

Cheers
