Comet 73P Fragment C passed in the same view as the Ring on Sunday night. I watched this from my computer screen via slooh.com.
If you're interested, here are two links, the first to a movie I put together animating slooh pics of the "pass" and the second, one of my jpegs with a little processing that shows the two in the same view.
