People end up as co-authors on papers for all sorts of reasons. Some co-authors contributed as much to the paper as the primary author. But most of the time the co-authors didn't do a whole lot (maybe just provided some data). Without knowing anything about the paper and how it was produced, I tend to assume the latter.

But as an undergraduate it is definitely something you can point to during interviews. Having already worked on a research project (even if it is just in a minor capacity) makes you more interesting as a candidate. And it serves as a nice entry point into the interview. From there one can discuss what exactly you contributed, what you have learned while doing so and so on.

So I would say: Notable, yes. Something special, no.
