J. B. Hutchings, A. P. Cowley and D. Crampton, Dominion Astrophysical Observatory, communicate: "Optical spectra obtained at Cerro Tololo Interamerican Observatory of the star 6" southwest of R 148 (cf. IAUC 3472) show extremely variable emission at 468.6 nm, narrow Balmer absorption and variable He I and He II absorption. Radial velocities of H and He II 468.6 nm vary over ~ 50 km/s from night to night, and the line intensities vary within a few hours. Photometry and further spectroscopy of the object are desirable."
