What propagation mode?

When we see short-skip on 6m into Europe we often associate this with Es.  But we are near the top if the solar cycle and we often see short-skip into Europe on lower frequencies like 20m, even in the quiet years. 

Now, I am no expert on propagation and wonder what mode of propagation many of these spots are? I presume Es, but maybe I am wrong? 50MHz seems too high for F2.
