Personally I try to keep up with any developments with the WOW! signal, it is not too hard to be honest, pretty slow going between informational releases there.
However, one should keep in mind that the
LGM-1 signal (and
CTA-102 signal) had a lesson to be learned with regards to a premature conclusion.
There were no premature scientific conclusions, as far as I am aware, concerning PSR B1919+21 (LGM-1), the first pulsar discovered, or CTA-102, one of the first quasars known. It was *suggested* that these *could* be extraterrestrial signals, which was perfectly true, based on what was known of them, early on. The TASS news agency made a too positive announcement that the latter source was a beacon of an extraterrestrial civilization, but this was not science, merely careless journalism, something that troubles this field, even today, regardless of the country involved.
*****All due honor to Dr. Jerry Ehman for having discovered the 'wow signal', but his idea that one of our own signals was reflected from a planet in our solar system seems very unlikely. None of the planets was at or near the coordinates at which the radio telescope was aimed at the time the signal was detected. The signal was quite strong (60 Janskys; the Sun, as a comparison has a typical flux density of 105 Janskys) This was 30 sigma above background noise. The planets are inefficient reflectors of radio waves.
