Jamming on PSK

I was on 15m PSK31 and in the process of calling PY3ED when a vicious jamming signal started up.

Jamming on 21MHz
As you can see, it did a good job of obliterating all signals. It seemed to be centered around 21.070MHz and extended for 50kHz or so in either direction.

I don't know how long it stayed on for because it was lunch time so I went to have something to eat. When I came back the interfering signal had gone.

Was it something local to me or has anyone else seen it?
