Abstract
We present VLA continuum (2, 3.6 and 20 cm) and line (H~I 21 cm, H92α and C92α) observations toward the cometary-like H~II region near the optical nebulosities GGD~12--15. The hydrogen recombination line (RRL) observations show that the ionized gas is undergoing a champagne flow. The carbon RRL and the 21~cm emission detected toward the H~II region have line center velocities similar to the velocity of the ambient molecular cloud. Both the carbon RRL and H~I emissions are interpreted as arising from the photodissociated gas around the H~II region. Using an isothermal model for photodissociated regions (PDRs) we estimate the physical parameters of this region.
