Abstract
We present a proper motion survey of the Galactic plane, using Isaac Newton Telescope (INT) Photometric H alpha Survey (IPHAS) data and Palomar Sky Survey (POSS)-I Schmidt plate data as a first epoch, that probes down to proper motions below 50 mas yr(-1). The IPHAS survey covers the northern plane (vertical bar b vertical bar < 5 degrees) with CCD photometry in the r, i and H alpha passbands. We examine roughly 1400 deg(2) of the IPHAS survey area and draw up a catalogue containing 103 058 objects with significant proper motions below 150 mas yr(-1) in the magnitude range 13.5 < r' < 19. Our survey sample contains large samples of white dwarfs and subdwarfs which can be identified using a reduced proper motion diagram. We also found several objects with IPHAS colours suggesting H alpha emission and significant proper motions. One is the known cataclysmic variable GD552; two are known DB white dwarfs and five others are found to be non-DA (DB and DC) white dwarfs, which were included in the H alpha emission line catalogue due to their lack of absorption in the H alpha narrow band.
