Kinematic Distances Information
Kinematic Distance (kpc): 9.8
Allowed Range (kpc): 7.2 to 14
Inferred Shell Size
  Shell Diameter (pc): 550
  Allowed Range (pc): 400 to 780
Distance Notes:
Seems associated with spiral structure but kinematic distances are too large for spiral structure in this direction (actually at 2.5 kpc not 10 kpc). May be affected dramatically by streaming motions. Kinematic distances could well be inaccurate.
