Progress on detection of gravitational waves?

[Agerhell]

Does anyone know how the progress is on the attempts to detect gravitational waves with interferometry?

As far as I know there are only null-results up to this date, but maybe I am misinformed?

The recent supernova in the galaxy Messier 101, should it generate gravitational waves of amplitude/wavelength detectable by current apparature? (It was a supernova of type 1a at a distance of 21 million light-years).

What kind of cosmic event must, according to general relativiy, if they take place not to far away generate gravitational waves that are detectable with the the apparatures of today?

Maybe someone working on LIGO or some other attempt to detect gravitational waves are present on physicsforums and is willing to share his/her thoughts?

I would think any confirmed detection would be headline news.

Yes, but still... A confirmation that some cosmic event that should generate detectable waves does not would still be interesting. "Now we now for sure that a cosmic event of type x at distance y does not generate waves within the current detectable wavelength-limits and above the current detectable amplitude threshold..."

If the apparature get sensitive enough and still no detections are made, then I guess one would have to rethink the theory of the nature of the waves... But how far are we from being forced to that today?
