Recent observations confirm that a fourteenth‐magnitude “peculiar” star in our galaxy is a bizarre object indeed, the like of which has not been seen before. Its spectrum exhibits hydrogen (Balmer) and helium emission lines with red and blue shifts indicating velocities up to 50 000 km/sec (0.17c), and these shifts vary roughly sinusoidally with a period of 164 days. The shifting lines are themselves comparatively narrow. The spectrum also contains unshifted hydrogen and helium lines.
