Scientific paper

M32-1 is a relatively bright planetary nebula in the small elliptical galaxy M32. Seven spectrophotometric scans of the nebula were obtained at Lick Observatory and at Kitt Peak National Observatory. The resulting emission-line flux ratios provide qualitative and quantitative indications of chemical abundances in the nebula. That the nitrogen-to-hydrogen emission-line ratio is large even though the nebula is of intermediate to moderately high excitation suggests a possible enrichment of nitrogen. The number abundance of helium to hydrogen is 0.10 + or - 0.05. Filter photometry obtained at Lick Observatory shows that the luminosity of M32-1 in the forbidden O III line at 5007 A is comparable to the luminosity of the brightest planetary nebulae in the Large Magellanic Cloud and in M31 and that the mass of ionized gas is approximately 0.09 solar mass for an assumed electron density of 10,000 per cu cm.
