Buil, Castanet, France, reports that an optical spectrogram (resolution 16000) of RS Oph, obtained on Feb. 14.21 UT with a 0.28-m Schmidt-Cassegrain reflector, shows a broad emission line of H-alpha (FWHM = 3930 km/s); the total width of the H-alpha line at the base is 7540 km/s. A narrow and intense double-peaked structure of H-alpha is present, with a red/blue-peak separation of 84 km/s; the intensity of the principal peak is 11.7 times that of the local continuum.
