Hell, I like such stuff:

Besides astronomical observations of this unique object, there is also this remote possibility: That this interloper is an interstellar survey probe, having perhaps dropped down to interplanetary-scale velocities in order to take data during its transit of our solar system, before going on to another star.

If it were such a probe, it might become unobservable  sooner than expected, when it sped up. I check frequently, but haven't found anything, so far, to indicate that Oumuamua has disappeared. Will check again for new observations, or the lack of same.

\Addendum-- Just checked the Minor Planet Circulars. The latest reported observation of Oumuamua is Nov. 20th, eight days ago. That short a hiatus don't necessarily tell us much. Previous gaps between observations  are similar in length. Past observations: Oct. 25, 26,27, 29. Nov. 1, 10, 13, 20.

Let's assume for a moment that the most unlikely outcome in scientific history turns out to be true and ʻOumuamua turns out to be artificial, surely then you would expect to see some evidence of manoeuvring as the vehicle passed through the solar system. It seems highly unlikely that the vehicle would just allow itself to pass through without taking a look at the most interesting planet in the solar system, the one with technological life. Instead it has passed through following only the laws of Newton and Kepler as it has done so. Odd behaviour for an interstellar spacecraft. Expected behaviour for an interstellar asteroid,

There is of course an other possibility, the builders of this spacecraft don't want us to know that it is artificial. It is pretending to be an asteroid as a form of camouflage. In which case it is not going to start accelerating again until after it is out of reach of our telescopes.

It seems highly unlikely that you are going to see any thing out of the ordinary since the two most logical conclusions for the behaviour of ʻOumuamua so far are that it is a natural object and, in the extraordinarily unlikely event that it isn't, it wants humanity to think it is a natural object.

Finally what do you expect to discover that the experts that are actually tracking this thing can't? Do you really think that all the world's astronomers will miss the first non-human made object ever to make a manoeuvre not consistent with Kepler and Newton? Do you really believe they are all that incompetent?

Speaking of SETI interest in Oumuamua, the SETI Institute's Allen Telescope Array is aimed at that mysterious object as I type this. They've concentrated all their observing power into one beam. It's usually three beams pointed at different objects. Link to their website:

Again, tonight, the Allen Telescope Array is monitoring Oumuamua.  At the moment they're listening around 8.52 Ghz. The position of the object is little changed from last night. The Right Ascension remains the same: 23.30 hours. The Declination has shifted from 6.98 to 7.03 degrees. Both positions are in the constellation Pisces.

Oumuamua is under observation again tonight, at the Allen Telescope Array. That's quite a lot of attention it's received lately.  It's apparently deemed at least as worthwhile, as a potential SETI target, as exoplanets, the usual points of interest. 

Position now Right Ascension 23.30 hours, Declination 7.21 degrees.

The Breakthrough Listen project will monitor Oumuamua for narrow-band (artificial) radio emissions for 10 hours today, starting at 20 hours GMT, about an hour and a quarter from now. They will listen with the hundred-meter-wide Green Bank Telescope, in West Virginia.

This radio telescope is reportedly sensitive enough to detect a signal of one watt strength, about the same as a mobile phone, from the current distance of Oumuamua.  This amounts to about 7 &1/2 times the sensitivity of the Allen Telescope Array, which the SETI Institute recently used to repeatedly monitor this object.

Do you mean a probe shaped like a rock? That's a great idea.

Let's see you joined in 2016 and I've been around since 2006, so it's my opinion that will matter here.

Seniority does not guarantee a higher level of comment quality. Your insane statement below, which you provided based on an opinion only, is a very good example for a comment of a very bad quality by a senoir member:

You guys are way too serious about yourselves. I can give a F!#$ about seniority. I was just picking on the person for calling me out with his one phrase statement which so often happens here.

I guess it would be considered manipulating your comment. Understood. I will make sure not to manipulate your comments. 

Do you feel better now? I hope you're happy with yourself. 

Merry Christmas or Happy Christmas depending on wherever in the F!$# you're from. haha
