Quilt of the ultracompact HII region G34.26+0.15 by Debra Shepherd (NRAO)

This quilt is a rendition of 3.6-cm (8.4 GHz) radio continuum data taken by D. Wood & E. Churchwell at the VLA (Van Buren et al. 1990, ApJ 353, 570) . Other images at 2 and 6 cm are published by Wood & Churchwell (1989), ApJS 69, 831. This object is the prototype for cometary, ultracompact HII regions; it is believed that a massive, early B star is forming within this cloud (Hunter et al. 1998), which is moving supersonically and creating a bow shock.

From Van Buren et al. (1990).
