A. Sanyal, Department of Physics and Astronomy, Howard University, communicates: "Spectra obtained on Feb. 8 at phase 0.54 (IAUC 3466) indicate the presence of a G8V absorption spectrum, blue-shifted by 140 km/s, in addition to Balmer H, He I and He II 468.6-nm emission. On Feb. 9 the H-beta emission full width was 1775 km/s, with possible P Cyg absorption at 1350 km/s. The radius of an assumed edge-on, circular, relative orbit is 1.1 x 10**6 km, indicating a mass of 1.38 Msol for the collapsed companion. A maximum limiting distance of 630 pc has been estimated for this high-galactic-latitude object."
