G189.1+3.0

Note: this is an archived version which has been superseded. The current SNR catalogue is at http://www.mrao.cam.ac.uk/surveys/snrs/

G189.1+3.0 IC443, 3C157

Right Ascension: 06 14 00
Declination: +22 36
Size (/arcmin): 45
Type: S
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.
Distance: Mean optical velocity suggests 0.7--1.5 kpc, association with S249 gives 1.5--2 kpc.
