G189.1+3.0 IC443, 3C157 (Green’s catalogue)
Right Ascension: 06 17 00 Declination: +22 34 Size (/arcmin): 45 Type: C Flux density at 1 GHz (/Jy): 160 Spectral Index: 0.36 Radio: Limb-brightened to NE, with faint
extension to the E. Optical: Brightest to the NE, with faint
filaments outside the NE boundary. X-ray: Shell, brightest to the NE, plus
compact source with nebula. Point sources: X-ray source and nebula
in S. Distance: Mean optical velocity suggests
0.7–1.5 kpc, association with S249 gives 1.5–2 kpc.

>_<: show No line broaden
The 24um emissions in the east are probably ralate with the Mcs at 100km/s

^_^. 12CO along with radio, partly along with X-ray
^_^.High 12co to 13co ratio >_<.no enough evidence to prove
the MC is shocked.

1. Discovered X-ray from ROSAT and XMM
2. Near the MASER velocity, find a shell in the east, which match along with radio,IR and X-ray, and the line show some broadening.
3. We need 12CO 2-1,3-2 observations to find the shocked MCs.
