Mendez, R. H. ; Niemela, V. S. Abstract Spectrograms of the central stars of the planetary nebulae NGC 246, He 2-131, and He 2-138 are described. Variations have been found in the spectra of the first two stars. The central star of He 2-138 has a BC0 Ib spectrum; this is the first case of a low-mass star showing 'OBC' characteristics.
