That's a recording of a receiver in Arizona on 22 mhz (shortwave)
The increased noise floor is the coronal mass ejection affecting the radio waves.
FYI this is very interesting as we're currently at the bottom of a 11 year sunspot cycle...where this type of stuff typically doesn't happen. The x6 today followed a X9 on the 5th which is a really bad storm. It's just hitting Earth today.
