GSH 048-05+045

Right Ascension (hh mm): 19 36
Declination (deg): 11.25
Reference Velocity (km/s): 44.95
Delta RA (hh mm): 00 27
Delta Dec (deg): 4.5
Delta V (km/s): 10.83
Mean Angular Diameter (deg): 4.90
Shape parameter: 0.64
Comments:
Based on how it appears across its velocity range, GSH 048-05+045 appears to be a large structure that contains GSH 047-03+040 (Ehlerova & Palous 2005), which is the smaller elongated feature at the southwest corner of our shell, as well as Heiles Supershell GSH 048-04+049 (Heiles 1979), which is likely the east portion of our shell. At lower velocities, GSH 048-05+045 appears to blow out into a larger (unseen) bubble.
