In the 01 September 2004 edition of the NewScientist there is an article
about an unexplained radio signal found by the SETI@home project.
(http://www.newscientist.com/news/nog...?id=ns99996341)

The article has little information about the nature of the signal.
They do talk about the wave length and the patch of sky it comes
from and that it had been detected three times. But they don't say
how many bits it is or how strong it is. I assume they didn't receive
a digital encyclopedia, they would then be sure of its intelligent
origin. But is the signal more than a single beep barely stronger than
background noise? Does any one have information about how different
from back ground noise theses signals are?
