We report high-resolution spectroscopy of the moderately reddened ( -->AV = 3) early-type star Cernis 52 located in a region of the Perseus molecular cloud complex with anomalous microwave emission. In addition to the presence of the most common diffuse interstellar bands (DIBs) we detect two new interstellar or circumstellar bands coincident to within 0.01% in wavelength with the two strongest bands of the naphthalene cation (C10H -->8+) as measured in gas-phase laboratory spectroscopy at low… Expand
