Query: Discovering Interacting Binaries with Halpha Surveys   A deep (R ~ 19.5) photographic Halpha Survey of the southern Galactic Plane
was recently completed using the UK Schmidt Telescope at the AAO. In addition,
we have recently started a similar, CCD-based survey of the northern Galactic
Plane using the Wide Field Camera on the INT. Both surveys aim to provide
information on many types of emission line objects, such as planetary nebulae,
luminous blue variables and interacting binaries.
  Here, we focus specifically on the ability of Halpha emission line surveys to
discover cataclysmic variables (CVs). Follow-up observations have already
begun, and we present initial spectra of a candidate CV discovered by these
surveys. We also present results from analyzing the properties of known CVs in
the Southern Survey. By calculating the recovery rate of these objects, we
estimate the efficiency of Halpha-based searches in finding CVs.
