Yes.. Earthquake in IL. The last time I remember this happening was June 28, 2004.

The USGS information page has more information on the quake, which they say was officially a 3.8 quake.

I did not feel this quake, though, this was also one of the few days where I did not wake up at like 4am from back issues. I’ve seen tweets from people (didn’t have that in 2004!) saying that they’ve felt it in wide ranging places from Rockford, IL, to suburban Chicago, to Milwaukee, WI!
