Hi Carissa,
One wave you might be talking about, and I'm not sure, but will give it a go. Check out this link from the NASA Soho site;

It describes what amounts to solar "quakes" on the Sun's surface! These events produce seismic-like waves seen in earthquakes, or those now often talked about ocean events, called tsunamis, that are large ocean waves as a result of earthquakes!
