> In 2012, on the 35th anniversary of the Wow! signal, the Arecibo Observatory was said to have beamed a digital stream towards Hipparcos 34511, 33277, and 43587.[45] The transmission consisted of approximately 10,000 Twitter messages solicited for the purpose by the National Geographic Channel, bearing the hashtag "#ChasingUFOs" (a promotion for one of the channel's TV series).[46] The sponsor also included a series of video vignettes featuring verbal messages from various celebrities.
What an inane, embarrassing "response", if the original was any attempt to communicate. (Sounds like it probably was not, but still...)

Who's to say that the original message was any less ridiculous?

Following tradition the message has to be video of a fascist rally.

I simply do not believe that the WOW signal mean anything at all.
I'm reminded of the exciting signal at Parkes Observatory that turned out to be the microwave oven making an astronomers lunch.
If all the modern sophisticated alien signal has detected zero then we really have to stop obsessing about the wow signal from 1977.

> The precise location in the sky where the signal apparently originated is uncertain due to the design of the Big Ear telescope, which featured two feed horns, each receiving a beam from slightly different directions, while following Earth's rotation. The Wow! signal was detected in one beam but not in the other[...]
This part intrigues me, or at least seems like an important piece of the puzzle, ruling out local causes of the signal that would affect both horns.
Four dozen + 1 = 7^2 years ago, our fathers received a signal...

Not sure if you're sarcastic but it's the starting point of the Three body problem.

Surely ironic and the book is "Contact".

What was the WoW signal in signal processing terms? Just a strong CW burst? Any modulation?
Asked differently, if I looked at this signal in an oscilloscope, would it be a perfect sine wave at the hydrogen line frequency?
That's got to be an alien transmitting that.

it's just a CW carrier with no observable modulation for 72 seconds, the time the telescope would be expected to observe a transmission based on the movement of the earth

A near-perfect sinewave is pretty much what you'd expect (and in fact will receive) at the H-line, since it represents a difference in quantum energy levels, specifically the hyperfine interaction due to flipping the electron-versus-proton spin direction. Any sort of modulation on a 1420-MHz signal would be much more interesting.
What was interesting about the Wow signal is simply how strong it was compared to the expected 1420 MHz background.
Radio astronomy is full of anecdotes like that. My favorite is the 2450 MHz emission that was found to be caused by people in the breakroom opening the microwave oven door before hitting the 'Stop' button.

Which sounds like swamp gas in space, but what do I know.
