Seti signal
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? Alain Fournier |

Lets hope some other stronger candidates come up (or that this one gets more reobservations). To answer my own question, it is a single beep (but observed on three different occasion at the same location). The signal is somewhat clear but over all not something that wouldn't be expected to happen randomly in all the background noise that has been screened by SETI@home. Alain Fournier |

There was something similar in the 60s, I believe. They called 'LGM'. It turned out that they had discovered the first pulsar and not Little Green Men. Eric : Alain Fournier |

And a major discovery, regardless. The the curious behavior of this signal (always starting at a particular frequency, and then drifting) suggests that it is some kind of local noise source. -- Michael Smith Network Applications www.netapps.com.au | +61 (0) 416 062 898 Web Hosting | Internet Services |

Why would a local noise drift behave that way? Local transmitter warming up/ My knowledge of radio transmitters is near to null and I have no reason not to believe you that a transmitter warming up would behave that way. But just to evaluate the likeliness of that I would like to know if you actually know that a transmitter warming up does behave that way, or that it might behave that way or is this just an educated guess from you. Also, do you have an explanation as to why that would happen when a particular point in the sky is observed? For my part, given the low grade of the signal and enormous amount of observations analyzed, I think it is quite possible that this is just some random variation in the background noise that looks like a signal. But if it were to be observed a few more time then the random variation theory takes a beating. In a such a case I would like to know more about local transmitters warming up. If that would also turn out to fail to explain the signals then I would like to know more about little green men :-) Alain Fournier |
