Monoceros Nebula

• Right Ascension: 06 39 00
• Declination: +06 30
• Size (/arcmin): 220
• Type: S
• Flux density at 1 GHz (/Jy): 140
• Spectral Index: 0.4

Radio: In complex region, parts may be HII regions.

Optical: Large ring, near Rosette nebula.

X-ray: Possibly detected.

Distance: Association with molecular cloud suggests 1.6 to 2.0 kpc, association with dust or and optical extinction suggests about 1.1 kpc.
