I calculate that geocentrically the magnitude +10.8 asteroid 15 Eunomia will appear to pass the magnitude +0.9 star Antares by only 43 arcseconds on 2014 SEP 17 at 04:29 UT (SEP 16 at 23:29 CDT).

I’ve created a related chart that can be viewed on my website at CurtRenz.com/asteroids.html

I realize that the brightness ratio between the two objects will be over 9000, and that closest approach can only be observed at night from western North America. But I thought it might be interesting for folks with telescopes to watch the two objects approaching each other before the glare of Antares possibly swallows Eunomia.

Photos and descriptions of the event would be welcome additions to this thread.

So 15 Eunomia will be near Antares for several days. The question is, at what point does Antares overwhelm the rock, rendering it unobservable? Let's find out.

We'll have to do that, Paulie. The conjunction is now only a week away.
