Consider

I thought EMP only propagated through atmosphere?

Also... a human nuke would seem pretty tame compared to what that little ball of fusion called the 'Sun' is putting out... Consider

No, an EMP can travel through space as well, since it is just electromagnetic radiation. In fact, CMEs are a major source of interference in satellite communications-

In actuality, not all that different from an EMP in the man-made sense, just made by the sun. As was mentioned, human-made nukes have proximity going for them. That ~93 M miles from the sun is still trouble for satellites, they "suffer" and sometimes die from the radiation. In fact, satellite lifetime, after on-board fuel considerations, usually depends on the amount of protective metal they have as shielding from that "little ball of fusion". As I am sure you are aware, that radiation is immense. Consider that one can get a sunburn in an exposure time as small as 1/2 hour, and that the sun is ~93 M miles away, and that you intercept an incredibly small amount of that energy.
