• FR I (plumed) radio galaxy at z=0.0169 (51/h Mpc, H = 100h km/s/Mpc)
• Rapidly expanding, then recollimating, jet and counterjet
• Northern jet base is brightest just before jet boundary "flares"
• Fainter, narrow inner jet close to central source
• Evidence for rapid slowdown of bulk relativistic outflow
• VLA 8 GHz data at 0.3 arcsec resolution
• Other images of 3C31 available here:
