  Aims. We analyze the LBN 978 HII region in order to study the HII/molecular
cloud interaction.
  Methods. We used the IAC-80 telescope to image the region with narrow-band
filters and the Very Large Array to obtain a radio continuum map at 3.6 cm. We
also used the DSS2 red images and the NRAO VLA Sky Survey at 20 cm.
  Results. We have discovered a new radial system of dark globules associated
with the LBN 978 HII region, containing a group of at least eight cometary
bright-rimmed globules with the same morphological type. The brightest source
is also detected in the radio continuum. Analysis of optical and radio emission
suggest that this object is photoionized by HD 47432, the central star of the
LBN 978 HII region.
