What is a Morton Wave on the Sun?

[davenn]

hi gang,

I have a have a solar video clip from the 8th Dec, 2006 showing an X9 flare and a "morton wave" spreading out across the surface of the sun.

Now to me this looks just like the hi speed shock wave that you can hi speed video from any LARGE explosion on earth.

The prob is, I have searched on "morton wave", "morton waves on the sun" and a few other variations, but cannot find any definitions of the term

Any thoughts ?

cheers
Dave
