This image shows you two dimmed supernova remnants positioned in the Auriga's pentagon. A vast curve-shaped one in lower right hand side is Sh2-223, and another a bit smaller one in upper left hand side has an ID of Sh2-224. Sh2-223 has been positioned about 3 degrees southeast of Capella, its length extends to about a degree. Sh2-224, lying at 2 degrees northeast of Sh2-223, has an elongated shape with a long axis of about 30 arc minutes.
