Abstract
We report spectroscopic observations of a new planetary nebula PM 1-322, which has not yet been identified. This object was found during a northern survey of post-AGB and planetary nebulae candidates selected from Garcia-Lario et al. (1997, A&AS, 126, 479) and Preite-Martinez (1988, A&AS, 76, 317). Here we present the main spectroscopic features includ- ing a list of the intensities of the identified emission lines. The main spectral characteristic of PM 1-322 is the presence of a very strong (O ) λ4363 emission line (I(OIII)4363/Hβ � 120) indicating high electron densities (log Ne > 6.0). A comparison with similar objects strongly suggests that PM 1-322 is a very young planetary nebula, although the posibility of a symbiotic nature can not be ruled out.
