Notes: Has been suggested as the remnant of the SN of AD185?

Radio: Ragged shell.

Optical: RCW 89 is the Halpha emitting region to the NW.

X-ray: Partial shell, central nebula and pulsar and possible ``jet".

Point sources: Radio and X-ray pulsar, plus IR compact source.

Distance: HI absorption indicates 4.2 kpc.
