Nice job Tony!
It's in quite a difficult position to image. You should forward the image to Spaceweather - because of the interest in this comet and its recent rapid changes, a couple of days ago they were calling for readers with pertinent images to submit them. The comet is not currently visible from the NHem, and there are not a lot of images around.
Just go to the Spaceweather page and click the 'Submit Your Images' link (scroll down, on the right).
