Abstract:
A method for searching new possible planetary nebulae among the
unidentified sources of the IRAS Point Source Catalog is described.
Sources were selected according to their far infrared colours,
proximity to galactic equator, and quality of the IRAS detection. A
catalog of 388 new possible planetary nebulae is presented and the
properties of the selected sample are discussed.
