For those skipping straight to the comments, they basically think it's 1 or more geostationary satellites that happen to be in the path of the observed star, Ross 128.

So what's the likelihood of a naturally occurring geostationary satellite vs one created by alien life?

I think they mean a man-made geostationary satellite.

You caught me! Thank you very much.

Interestingly, we've surrounded our planet by sputniks which were invented as a step to the stars but sometimes they make our interstellar eyesight less sharp.

A good opportunity to ask: What does everyone here think the Wow signal was? https://en.wikipedia.org/wiki/Wow!_signal

I know it's just speculation, but it's fun to speculate. What could it have been? Could any natural phenomena generate a signal like that?

It certainly wasn't a message aimed at us, or anything like that. But it did happen, so I can't help but wonder what it likely was.

People think it's been solved: https://www.google.com/search?q=wow+signal+solved

And apparently the Director of the OSU SETI program disagrees with those people:

Nice find, looks like it's still a mystery.

Nice, very glad to see the telescope is still being used for some cool stuff.

It's probably someone microwaving lunch.
