Query: Deep inelastic events containing a forward photon as a probe of small
  $x$ dynamics   We calculate the rate of producing deep inelastic events containing an
energetic isolated forward photon at HERA. We quantify the enhancement arising
from the leading $\log 1/x$ gluon emissions with a view to using such events to
identify the underlying dynamics.
