G357.7−0.1

MSH 17−39

• Right Ascension: 17 40 29
• Declination: −30 58
• Size (/arcmin): 8×3?
• Type: ?
• Flux density at 1 GHz (/Jy): 37
• Spectral Index: 0.4

Notes: Has been suggested that this is not a SNR.

Radio: Multiple arcs and filaments, brighter to NW `head'.

X-ray: Detected from NW `head', and SW `tail'.

Distance: HI absorption suggests beyond Galactic Centre.
